Poolability test

WebIf the test statistic has a p-value below an appropriate threshold (e.g. p < 0.05) then the null hypothesis of homoskedasticity is rejected and heteroskedasticity assumed. If the Breusch–Pagan test shows that there is conditional heteroskedasticity, one could either use weighted least squares (if the source of heteroskedasticity is known) or use … WebJun 15, 2024 · Now Stata gives the poolability test result after the reg ression with the factor variable i.Time: testparm i.Time /*(iii) Slope coefficients constant but intercept varies o ver companies and time.
