This collection of papers delivered at the Fifth International Symposium in Economic Theory and Econometrics in 1988 is devoted to the estimation and testing of models that impose relatively weak restrictions on the stochastic behaviour of data. Particularly in highly non-linear models, empirical results are very sensitive to the choice of the parametric form of the distribution of the observable variables, and often nonparametric and semiparametric models are a preferable alternative. Methods and applications that do not require string parametric assumptions for their validity, that are based on kernels and on series expansions, and methods for independent and dependent observations are investigated and developed in these essays by renowned econometricians.

Misspecification tests play an important role in detecting unreliable and inadequate economic models. This book brings together many results from the growing literature in econometrics on misspecification testing. It provides theoretical analyses and convenient methods for application. The main emphasis is on the Lagrange multiplier principle, which provides considerable unification, although several other approaches are also considered. The author also examines general checks for model adequacy that do not involve formulation of an alternative hypothesis. General and specific tests are discussed in the context of multiple regression models, systems of simultaneous equations, and models with qualitative or limited dependent variables.

Probability theory is nowadays applied in a huge variety of fields including physics, engineering, biology, economics and the social sciences. This book is a modern, lively and rigorous account which has Doob's theory of martingales in discrete time as its main theme. It proves important results such as Kolmogorov's Strong Law of Large Numbers and the Three-Series Theorem by martingale techniques, and the Central Limit Theorem via the use of characteristic functions. A distinguishing feature is its determination to keep the probability flowing at a nice tempo. It achieves this by being selective rather than encyclopaedic, presenting only what is essential to understand the fundamentals; and it assumes certain key results from measure theory in the main text. These measure-theoretic results are proved in full in appendices, so that the book is completely self-contained. The book is written for students, not for researchers, and has evolved through several years of class testing. Exercis

The technique of allometry investigates the effects of size on such variables as food intake, energy requirements, growth rates and age at first reproduction. This book brings together much of what is known about the consequences of size and provides a new and mathematically rigorous framework within which many quantitative predictions are made and tested using published and unpublished data. Explanations are proposed for many previously unexplained phenomena such as why in some species females are thousands of times heavier than males, whereas in no species are males more than about eight times heavier than females. The models presented afford a synthesis of the effects of size and open up pathways for further theoretical investigation and experimental testing. Care has been taken to give verbal presentations of all the mathematical conclusions to ensure that the text is widely intelligible.

This successful book, now available in paperback, provides academics and researchers with a clear set of prescriptions for estimating, testing and probing interactions in regression models. Including

This volume brings together eight original essays selected to provide an overview of the developments in the spatial theory of voting. The spatial theory of self-interest and explores the consequences of this assumption for elite behaviour and for the choices voters make in representative and direct democracies. The book summarizes work in eight major areas: elections with possible entry by new candidates who have policy preferences, experimental testing of spatial models of committees and elections, elections with imperfect information about voting intentions, voting on alternatives that are linked to future decisions, elections with candidates who have policy preferences, experimental testing of spatial manoeuvres designed to alter voting outcomes, elections with experimental testing of spatial models of committees and elections, elections with imperfect information about voting intentions, voting on alternatives that are linked to future decisions, elections with more than two candi

Recent advances in establishing the nature and scope of estimators in econometrics have shed more light on the importance of instrumental variables. In this book, the authors argue that such methods may be regarded as a strong organizing principle for a wide variety of estimation and hypothesis testing problems in econometrics and statistics. In support of this claim they present and develop the methodology of instrumental variables in its most general and explanatory form. They show, for instance, that techniques commonly used to handle simultaneity and related problems can be reduced to one of two generic variables of instrumental variables estimators, allowing them to explore further the conditions under which different proposed estimators are efficient.

The advent of electronic computing permits the empirical analysis of economic models of far greater subtlety and rigour than before, when many interesting ideas were not followed up because the calculations involved made this impracticable. The estimation and testing of these more intricate models is usually based on the method of Maximum Likelihood, which is a well-established branch of mathematical statistics. Its use in econometrics has led to the development of a number of special techniques; the specific conditions of econometric research moreover demand certain changes in the interpretation of the basic argument. This book is a self-contained introduction to this field. It consists of three parts. The first deals with general features of Maximum Likelihood methods; the second with linear and nonlinear regression; and the third with discrete choice and related micro-economic models. Readers should already be familiar with elementary statistical theory, with applied econometric res

Holographic and speckle interferometry are optical techniques which use lasers to make non-contracting field view measurements at a sensitivity of the wavelength of light on optically rough (i.e. non-mirrored) surfaces. They may be used to measure static or dynamic displacements, the shape of objects, and refractive index variations of transparent media. As such, these techniques have been applied to the solution of a wide range of problems in strain and vibrational analysis, non-destructive testing (NDT), component inspection and design analysis and fluid flow visualisation. This book provides a self-contained, unified, theoretical analysis of the basic principles and associated opto-electronic techniques (for example Electronic Speckle Pattern Interferometry). In addition, a detailed discussion of experimental design and practical application to the solution of physical problems is presented. In this new edition, the authors have taken the opportunity to include a much more coherent

The potato is one of the world's most important food crops. It produces more nutritious food from less land in a shorter time than any other major crop. Therefore advances in the production of new potato varieties will greatly contribute to the world's food supply. The book outlines strategies used in the breeding and testing of potato varieties. It considers prospects for varietal improvement using both traditional and new techniques, including genetic manipulation, tissue culture and protoplast fusion. Opportunities for breeding varieties suitable for propagation from true seed, of particular significance to the agricultural systems of developing countries, are also featured, together with an extensive and bibliography. The book is based on the proceedings of a joint meeting of EAPR and EUCARPIA at King's College, Cambridge, December 1985. It contains contributions from many leading authorities in potato breeding and variety assessment throughout the world, and will interest post-gra

Enlarged and updated in 1983, this is the second edition of Dr Steel's popular textbook on interferometry. The text has been revised throughout and major additions have been made to reflect the phenomenal growth of laser techniques and applications. The book provides a general treatment that brings together the many different applications of the interference of light waves, light being used in its most general sense to include all electromagnetic radiation. The applications can cover precise measurement of length, the testing of optical components against a computed hologram, measurements of atmospheric pollution by infrared spectroscopy and many of the methods of radio astronomy and the measurement of size of visible stars. These apparently unrelated methods have a common theory, which the book presents and extends to each main field of application. It shows workers in one field how their problems relate to those in other fields, where they may have been solved already. The book will

First published in 1985, this book presents a 'triarchic' theory of human intelligence that goes beyond IQ in its conceptualisation and implications for assessment. The theory has three parts. The first deals with relations between intelligence and experience; the second, with relations between intelligence and the external world; the third part with relations between intelligence and the internal world of the individual. Robert J. Sternberg begins by sketching the history of intelligence research. He then outlines the three parts of the theory and adduces supporting evidence, including evidence from studies of 'practical' as well as 'academic' intelligence. He considers the issues raised by exceptional intelligence and by intelligence testing. His conclusions will be of interest to all those concerned with intelligence, its development and its measurement.

This paperback edition of Dr Hudson's advanced textbook presents the theory of small disturbances propagating through solids. The material is set out carefully in mathematical detail. The linearised theory of elasticity has now been replaced by a more fundamental approach based on a generalised theory of continuum mechanics. Despite this change of emphasis in solid mechanics there remain important areas of physics in which the linear theory is clearly of fundamental importance, especially in seismology, noise analysis and the non-destructive testing of materials. This is a textbook suitable for advanced undergraduates in a variety of disciplines, including applied mathematics, applied physics, geophysics and structural and civil engineering. The book is of particular interest to seismologists and physicists engaged in non-destructive testing.

Trainee and practising teachers will benefit enormously from this practical handbook. It includes: classroom techniques covering all four skills; testing; problem classes; phonetics; and syllabus desi

This is practical compilation of tables required for the usual tests based on classical probability distributions and for the more commonly used distribution-free (non-paraetric) tests, which are important in the behavioural sciences. In addition to the tables there is a substantial amount of explanatory text with diagrams and examples. The treatment is non-mathematical and the nature and use of the tabulated functions is clearly explained. The usual (Neymann-Pearson) procedure for testing statistical hypotheses is simply described and numerical examples given. The tables have been designed for use with calculators, and, since most calculators have keys for logarithms, squares, square-roots and reciprocal, these functions have not been included. This, and the fact that maximum use has been made of the space available, has enabled the book to be compact while remaining fully comprehensive. The tables will be invaluable to students in the social, biological and physical sciences and also

Social experimentation is a tool that enables economists and policy makers to test proposed economic policies in the real world. Instead of testing policies by analytical methods or by laboratory simulation, the policies are tested on people who would be affected were these policies implemented. The authors describe how such social experiments are set up and carried out, and consider the advantages and disadvantages of social experimentation relative to other means of evaluating economic and social policies. The main part of the book is a review and a critical evaluation of the principal social experiments in economics that have been carried out in the United States, where this method has been used most extensively. The authors examine in detail the first large-scale experiment in the United States (the New Jersey Income Maintenance Experiment) and subsequent experiments with the labour force, electricity rates, and cash housing allowances. A consideration of the social utility of soci

Written primarily for students of medicine, pharmacy, and pharmacology, this introductory book provides a concise summary of the principles that underlie the science of pharmacology. It presents the basic concepts required for understanding the use, mechanisms of action, toxicity and side effects, and therapeutic application of drugs in man. Thus the book may also be of interest to medical practitioners and to biological and medical scientists. Among topics covered are the sources of drugs, the way they are administered and dealt with in the body, as well as concepts about the nature of their actions. The last include their chemical interactions with components of cells and the manner in which these lead to therapeutically desirable as well as undesirable and even toxic effects. In addition, clinically related subjects, such as drug interactions, teratogenic and carcinogenic effects are discussed. The development and testing of new drugs are also described. For easy reference, at the b

First published in 1979, this book examines past thought and research about the social and psychological causes of juvenile delinquency in Western society. The first few chapters summarise major delinquency theories and survey an extensive list of studies that demonstrate those theories. The author then develops a single model of individual causation from the divergent theoretical traditions. The model includes such variables as social class, parent-child relations, school experiences, strain, peer relations, personal values and the perceived risk of being caught in lawbreaking. Testing the model with information from 734 large-city adolescents results in several innovations in the measurement and conceptualisation of key variables in delinquency research. In his search for a better understanding of delinquency, the author shows the usefulness of examining the impact of all the variables at once and finds that the major theories of delinquency complement rather than contradict one anot

Many students of physical and applied science and of engineering find difficulty in copying with the mathematics necessary for the quantitative manipulation of the physical concepts they are atudying in their main course. This book is designed to help first and second year under-graduates at universities and polytechnics, as well as technical college students, to find their feet in the important mathematical methods they will need. Throughout the text the physical relevance of the mathematics is constantly stressed and, where it is helpful, use has been made of pictorial mathematics and qualitative verbal descriptions instead of over-compact mathematical symbolism. Topics are presented in three stages: a qualitative introduction, a more formal presentation and an explicit check or worked example. There are many exercises included in the text which are aimed at testing a student's understanding and building his confidence progressively throughout each piece of work.
