Troubleshooting
Problem
I have used the SPSS Logistic Regression procedure to test a model and found that the model chi-square had a very low significance level. However, the classification table shows that all of the cases were predicted to have values of 0. This seems to suggest that the model was not effective at all. The ratio of cases with 0 on the dependent variable (DV) to cases with 1 was about 10 to 1. Does this relatively low frequency of 1s on the DV affect the predictive capability of the model?
