Key Concepts and Terms Types of variables . In log-linear analysis, variables may be factors, dependents, covariates, contrasts, or cell structure variables. Not each type of log-linear procedure supports all types. Factors , also known as "response variables," are categorical variables which define rows and columns in a crosstabulation table.In hierarchical loglinear models in SPSS, 10 factors are possible and the researcher can specify which levels of each to analyse. In probit models, the factor's levels are used to define subgroups for analysis.
