Hi,

I have big problem. I am going to run over 300 regressions and to do it one after one is to time consuming (as I want to add more data to analyses).
My data are in 30 different tabs containing Y and X values, the problem is that I need to do it in every tab for different time periods, meaning I have over 3000 (in every tab) observations and going to do 12 regressions from that sample and in every tab there will be different start and stop observation, however the number of observations in every regression is the same. Is it possible to record a macro to do it or program it in VBA?
