Dear Greta. You pushed me to try regression, thanks for it. Reorganizing the data by original observations was extra good resulted, thanks to you. Im satisfied both regression and logit models. Thanks for all helps..
Odds ratios and the rest are all the same in interpretting, said hlsmith.
For now, do you recommend me comparing both models -regression and firthlogit- in my study? Or should i use only one..
Funny enough. I did not know you could input data like Greta showed in post #7. That entry method is going to save me a lot of hassle. I had previously only recallwed the method where you use many "' around about everything.
