Hi,

Can the Firth method be applied to multinomial logistic regression? I am using it and I am having convergence issues - Firth was supposed to fix that for me:/.
Can someone advice?

Thanks in advance!

If you are asking about the STATS FIRTHLOG extension command in Statistics, the underlying R module that it uses only supports binary logistic.  Sorry.

If your response variable is actually ordinal, you could use ordinal regression (PLUM).
