This book was released on 2013 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work deal with biased estimation methods for estimating the parameters of general linear regression model when the data are ill-conditioned. We focus our attention on ordinary and generalized ridge regression estimators, Jackknife ridge estimators and principal components estimators. In chapter one introduction and historical review In chapter two basic concepts, definitions on linear regression model are presented. Moreover, the statistical properties of the ordinary least squares estimators are presented. Classes of biased estimators are discussed in chapter three when the data suffer from the multicollinearity problem. The procedures discussed in the preceding chapters were applied in chapter four to perform the regression analysis employing the data obtained from Midland Refineries Company in Iraq, for 12 years period in order to determine the effect of six different factors on the productivity of labor. The statistical programs, SPSS, and Minitab were employed to perform the required calculations.

This book was released on 2018-07-15 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several ways for detection and assessment of collinearity in measured data are discussed. Because data collinearity usually results in poor least squares estimates, two estimation techniques which can limit a damaging effect of collinearity are presented. These two techniques, the principal components regression and mixed estimation, belong to a class of biased estimation techniques. Detection and assessment of data collinearity and the two biased estimation techniques are demonstrated in two examples using flight test data from longitudinal maneuvers of an experimental aircraft. The eigensystem analysis and parameter variance decomposition appeared to be a promising tool for collinearity evaluation. The biased estimators had far better accuracy than the results from the ordinary least squares technique. Klein, Vladislav Unspecified Center RTOP 505-66-01-02...

Book excerpt: Biased estimation in regression has experienced a tremendous growth in popularity since Hoerl and Kennard's formalization of ridge regression. Along with the interest in biased regression, many research efforts over the last ten years have extended both the theory and application of these methodologies. So too, criticisms have arisen which focus on the incompleteness of the theoretical results and on exaggerated claims about the merits of biased estimators. Rather than attempting to arbitrate these opposing views, this article discusses biased estimation with special emphasis on its ultimate justification: application to real problems. Advantages and disadvantages of three biased estimators (principal component, latent root, and ridge regression estimators) are discussed and illustrated through a comprehensive analysis of a data set on automobile emissions. From the discussion and analysis it is hoped that a more balanced perspective on the application of biased estimation will be fostered. (Author).

Book excerpt: This report covers activities of the principal investigator and his research collaborators from 1 July 1975 to 30 June 1976 on Grant No. AFOSR 75-2871 sponsored by the Air Force Office of Scientific Research. Included in the report are abstracts of completed research papers, outlines of research in progress, and a summary of other research activities accomplished during the grant period. The emphasis of completed research has been on comparing various properties of competing regression estimators. Current and future research topics are aimed at improving the potential of the estimators judged most promising in the above studies, particularly the latent root and principal component estimators.

Available in PDF, EPUB and Kindle. Book excerpt: The recent interest in biased estimation procedures in multiple linear regression arises from the large variances of the least squares estimators (unbiased) of the regression coefficients when multicollinearities are present. The biased estimation procedures greatly reduce this variance at the cost of some bias. It is the purpose of this paper to look at this bias with reference to the nature of the specific problem being investigated. (Author).

Download or read book Lectures on Probability Theory and Mathematical Statistics - 3rd Edition written by Marco Taboga and published by Createspace Independent Publishing Platform. This book was released on 2017-12-08 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is a collection of 80 short and self-contained lectures covering most of the topics that are usually taught in intermediate courses in probability theory and mathematical statistics. There are hundreds of examples, solved exercises and detailed derivations of important results. The step-by-step approach makes the book easy to understand and ideal for self-study. One of the main aims of the book is to be a time saver: it contains several results and proofs, especially on probability distributions, that are hard to find in standard references and are scattered here and there in more specialistic books. The topics covered by the book are as follows. PART 1 - MATHEMATICAL TOOLS: set theory, permutations, combinations, partitions, sequences and limits, review of differentiation and integration rules, the Gamma and Beta functions. PART 2 - FUNDAMENTALS OF PROBABILITY: events, probability, independence, conditional probability, Bayes' rule, random variables and random vectors, expected value, variance, covariance, correlation, covariance matrix, conditional distributions and conditional expectation, independent variables, indicator functions. PART 3 - ADDITIONAL TOPICS IN PROBABILITY THEORY: probabilistic inequalities, construction of probability distributions, transformations of probability distributions, moments and cross-moments, moment generating functions, characteristic functions. PART 4 - PROBABILITY DISTRIBUTIONS: Bernoulli, binomial, Poisson, uniform, exponential, normal, Chi-square, Gamma, Student's t, F, multinomial, multivariate normal, multivariate Student's t, Wishart. PART 5 - MORE DETAILS ABOUT THE NORMAL DISTRIBUTION: linear combinations, quadratic forms, partitions. PART 6 - ASYMPTOTIC THEORY: sequences of random vectors and random variables, pointwise convergence, almost sure convergence, convergence in probability, mean-square convergence, convergence in distribution, relations between modes of convergence, Laws of Large Numbers, Central Limit Theorems, Continuous Mapping Theorem, Slutsky's Theorem. PART 7 - FUNDAMENTALS OF STATISTICS: statistical inference, point estimation, set estimation, hypothesis testing, statistical inferences about the mean, statistical inferences about the variance.
