课程内容：

This course takes an easy-to-understand look at a statistical approach called the person-centered method. Instead of analyzing means, variances, and covariances of scale scores as in the common variable-centered approach, the person-centered approach uses contingency tables to examine persons or objects grouped according to their characteristic patterns or configurations. In contingency tables, the observed patterns are ordered by their indices; a certain position in a table, denoted by a pattern or configuration, is called a cell. 

The main focus of the course will be on configural frequency analysis (CFA; Stemmler, 2014; von Eye, 2002), which is a statistical method that looks for over- and under-frequented cells or patterns. A pattern or configuration that contains more observed cases than expected is called a type; a pattern or configuration that is observed less frequently than expected is called an antitype. CFA resembles log-linear modeling: log-linear modeling seeks to find a fitting model including all important variables; instead of fitting a model, CFA examines the significant residuals of a log-linear model.
