WebApr 13, 2024 · Thanks): now I see the issue. If you run the Stata code I provided you with in my previous post, the F-test automatically reported as a footnote in result table tells you that -xtreg, fe- is actually better than pooled -ols-. For -hausman- specification test, expanding on the previous Stata code, you may want to try: Code: WebT-test Stata Annotated Output. The ttest command performs t-tests for one sample, two samples and paired observations. The single-sample t-test compares the mean of the sample to a given number (which you supply). The independent samples t-test compares the difference in the means from the two groups to a given value (usually 0). iowatelecom.net email login
