Hi Nick,
that is great, thanks, what kind of link functions? meanwhile, I am very new to Stata and just collected my data for my phd however still struggling with regression analysis. it seems, it will be difficult than what I expected. How can i find a complete list of activities to be done during a regression / step by step journey ? it seems,  i am finding something new everyday. thanks in advance.







kind regards
