Chi Square Mathematical Methods for Physics and Engineering by Ken Riley, The new edition of this highly acclaimed textbook contains several major additions, including more than four hundred new exercises (with hints and answers). To match the mathematical preparation of current senior college and university entrants, the authors have included a preliminary chapter covering areas such as polynomial equations, trigonometric identities, coordinate geometry, partial fractions, binomial expansions, induction, and the proof of necessary and sufficient conditions. Elsewhere, matrix decompositions, nearly-singular matrices and non-square sets of linear equations are treated in detail. The presentation of probability has been reorganized and greatly extended, and includes all physically important distributions. New topics covered in a separate statistics chapter include estimator efficiency, distributions of samples, t- and F- tests for comparing means and variances, applications of the chi-squared distribution, and maximum likelihood and least-squares fitting. In other chapters the following topics have been added: linear recurrence relations, curvature, envelopes, curve-sketching, and more refined numerical methods.
Intermediate Reader of Modern Chinese, Set by Chi-P'ing Chou, This textbook, prepared for American students who have already completed two semesters of Chinese, does not "talk down" to the student, and its contemporary subject matter will provoke classroom discussion. Successfully encouraging speaking as well as reading practice, the work progresses from correspondence and dialogue to short essays. Lessons 1 through 10 focus on college life in the United States, 11 through 15 concern political and social issues in contemporary China, and 16 through 20 present biographies of three well-known figures in Chinese intellectual history and analyses of the Chinese Democracy Movement and the Tiananmen Square incident. Lessons 21 and 22 deal with Chinese translations of foreign place names and the Gulf War and are designed to accustom students to reading Chinese newspapers. The lessons in this text offer sufficient material for a two-semester course with five contact hours per week. For the text and vocabulary traditional and simplified characters are juxtaposed. The exercises of each lesson are included in the vocabulary volume. An index to the glossary is included. Audio and video materials are available for use with this text. For further information, contact the Chinese Linguistics Project, 231 Palmer Hall, Princeton University, Princeton, N.J. 08544. (609-258-4269).
Pearson's chi-square test - Pearson's chi-square test (χ2) is one of a variety of chi-square tests – statistical procedures whose results are evaluated by reference to the chi-square distribution. It tests a null hypothesis that the relative frequencies of occurrence of observed events follow a specified frequency distribution. Chi-square test - A chi-square test is any statistical hypothesis test in which the test statistic has a chi-square distribution if the null hypothesis is true. These include: Inverse-chi-square distribution - {\Gamma(\nu/2)}\,x^{-\nu/2-1} e^{-1/(2 x)}| Chi-square distribution - {\Gamma(k/2)} x^{k/2 - 1} e^{-x/2}\,| chisquare
