Figure 2.6 Categorical Regression Output dialog box
Tables. Produces tables for:
Multiple R. Includes R 2 , adjusted R 2 , and adjusted R 2 taking the optimal scaling into
account.
Coefficients. This option gives three tables: a Coefficients table that includes betas,
standard error of the betas, t values, and significance; a Coefficients-Optimal Scaling
table with the standard error of the betas taking the optimal scaling degrees of freedom
into account; and a table with the zero-order, part, and partial correlation, Pratt’s
relative importance measure for the transformed predictors, and the tolerance before
and after transformation.
Iteration history. For each iteration, including the starting values for the algorithm,
the multiple R and regression error are shown. The increase in multiple R is listed
starting from the first iteration.
Correlations of the original variables. A matrix showing the correlations between the
untransformed variables is displayed.
Correlations of the transformed variables. A matrix showing the correlations
between the transformed variables is displayed.
