<> " How can I figure out the minimum sample size per each subgroup required to run correct regression (OLS)?" How is a "correct regression" defined theoretically? Stata does have commands like -h sampsi-, but apparently you are looking for something else?

Mai 2010 16:12 An: statalist@hsphsun2.harvard.edu Betreff: st: Sample size Dear Statalist I have a sample of about 193 corporations; this sample is composed by: - a subgroup of 139 corporations (subgroup A) - a subgroup of 54 corporations (subgroup B), identified by a dummy SUBG I run interactions (i.e., the dummy SUBG x indep var); I also run a chow test. Do you think that 54 companies in the interacting subsample are not enough? How can I figure out the minimum sample size per each subgroup required to run correct regression (OLS)?
