Multiple regression

Postby tonios » Fri Aug 14, 2015 11:12 am

Hi guys, I'm required to estimate a regression model to identify the effects of three determinants on company size for 20 companies during 6 years data.
Is it possible to build such a model in SPSS or it requires a different software? If no, could please help with explanation?
Thanks in advance!

how are your determinants measured? (e.g., ordinal, nominal, scale etc)?
Do you have your determinants measured at 1 timepoint or multiple timepoints?

I think you need a repeated measures model, which is also possible in spss, because your observations are not independent because they are about the same companies in multiple years.
It does seem likely that your sample size is way too small, for whathever analysis you want to do.
