I have a question about multinomial regression using spss. I have a dependent variable of 3 categories and other independent variable which are also categories and on scale (age). I used automatic coding using spss then I run the the multinomial regression and get this warning" Unexpected singularities in the Hessian matrix are encountered. This indicates that either some predictor variables should be excluded or some categories should be merged"

and also this warning" There are 372 (62.9%) cells (i.e., dependent variable levels by subpopulations) with zero frequencies."

I don't have empty cells.

Can anyone help me please as how to proceed.
