Hi,I was attempting to run a multinomial logistic regression with 665 sample size and only 7 events. Got this resulting message "The maximum likelihood estimate may not exist. The multinomial logit model cannot be estimated."Opted to use penalized likelihood (Firth's method) for alternative estimation to reduce the bias but it seemed that Firth's method is only available in binary logit model for xlstat.I'd like to ask if there is any workaround or solution for this. Or maybe I'm doing something wrong or missed out on something. Thank you in advance.
