Model Diagnostics

After building a model, you need to determine whether it reasonably approximates the behavior of your data.

Tests of Model Fit. The Binary Logistic Regression procedure reports the Hosmer-Lemeshow goodness-of-fit statstic.

Residual Plots. Using variables specified in the Save dialog box, you can construct various diagnostic plots. Two helpful plots are the change in deviance versus predicted probabilities and Cook's distances versus predicted probabilities.
