Hi!
Thanks in advance for any help..
I have a regression which looks like Y c X (X-squared)k . k is a dummy variable for data within a specific time range. So I have one independent for most of my series, and for the rest I have that same independnet and that independent squared. I hope thats clear. Anyway when I regress it i get the "near singular matrix" error....
Any advice greatly appreciated.

Take a look at k*x^2 and see if it turns out to be what you want. Odds are you have a sample error or a typo.

I tried everyhting, finally settled on a completely differnt model. Thanks though!
