Loglinear Analysis Define Range dialog box
You must indicate the range of categories for each factor variable. Values for Minimum
and Maximum correspond to the lowest and highest categories of the factor variable.
Both values must be integers, and the minimum value must be less than the maximum
value. Cases with values outside of the bounds are excluded. For example, if you
specify a minimum value of 1 and a maximum value of 3, only the values 1, 2, and 3
are used. Repeat this process for each factor variable.
Loglinear Analysis Model
Figure 5-3
Loglinear Analysis Model dialog box
Specify Model. A saturated model contains all factor main effects and all factor-by-factor
interactions. Select
Custom to specify a generating class for an unsaturated model.
Generating Class. A generating class is a list of the highest-order terms in which factors
appear. SPSS builds a hierarchical model containing the terms that define the
generating class and all lower-order relatives. Suppose you select variables A, B, and C
