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 Ozgur Ozdemir T: +44 (0) 75 0332 9865 E: ozdemirozgur@hotmail.com<mailto:ozdemirozgur@hotmail.com> Skype : ozgurozdemir2005 ---------------------------------------- > Date: Thu, 22 Sep 2011 12:38:44 +0100 > Subject: Re: st: qladder > From: njcoxstata@gmail.com > To: statalist@hsphsun2.harvard.edu > > It's enough that some are real zeros for the transformations concerned > to be invalid.
