Does anyone have any rules of thumb on this?
It seems to me when I use binary logistic regression and the smaller category in the outcome goes much below 100, I start to get extremely high Wald test statistics and very large coefficients, even though they should as coefficient.
My IVs are standard demographics/SES indicators - gender, age, education (3 dummies), income, social class (4 dummies).
Any help much appreciated.
