Basic Testing for Categorical Data
This chapter first discusses tests of hypotheses pertaining to the probability of a binomial distribution and gives a brief review of the fundamental concepts of tests of hypotheses. Exact, randomized, and asymptotic tests are considered. The Pearson chi-squared and likelihood ratio statistics are introduced for tests of fit. The concept of independence, which will play a central role in later chapters of the book, is also introduced for the simple case of two-way tables and tests of independence are discussed.
