Abstract: Abstract This book is about categorical date, i.e. data which can only take a finite or countable number of values. Typical situations, which give rise to a statistical analysis of categorical data are the following: Consider first a population of individuals. For each of these a variable can be measured for which the possible values are the numbers from 1 to m. The variable may for example be the social class, the individual belongs to, with the possible social classes numbered 1 to 5. From the population a sample of n individuals is selected at random and for each of the sampled individuals the social class, he or she belongs to, is observed. The data then consists of the counts x1,...x5 of number of individuals observed in each social class. Based on this data set one statistical problem is to estimate the percentages of individuals in the total population, which belong to the five social classes. Another would be to test hypotheses concerning the distribution of the population on social classes.
