Dear all, Using STATA 11. Running a logit model for three cross sectional set (three years) to examine a disparity question between two groups xi: logit y i.group I ran this for each year and getting the coefficient for group 2 (group 1 is the reference). Is there a way in STATA to compare the coefficient with each other?

Nick n.j.cox@durham.ac.uk Wael Wael Thanks for your response. I am using STATA 11. I used the logit syntax for each year with group 1 as a reference. I would like to compare the difference i found in the first year with the following year output.

This is really a fishing expedition on your part in which you seek ideas on what to do in a project as yet undefined. That kind of question is not disallowed, and you may get some useful advice, but on the whole your chance of getting good advice would be much increased if you gave much more detail. 2. You are already using some specific commands. That kind of question is more likely to get answers, but again only with supply of Stata detail. For example, you don't even say what model or models you are using or contemplating.Wael WaelI am running a serial cross sectional study to examine disparities between two groups. I want to compare my model output in year 1 with the following year. (i.e. is the gap in disparities increasing or decreasing) Any ideas on how to do this in STATA would be appreciated.* * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/* * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
