Analysis of categorical data
The analysis of counts, rather than measurements, where people or things are classified simultaneously by two or more attributes. Categorical variables may be ordinal (categories are naturally orders) or nominal (categories have no natural order). The counts are conveniently arranged in a table, known as a contingency table. The pattern of association may be measured by computing measures of association or by fitting a log-linear model
