27 нояб. 2013 г. · Therefore, a robust F-test, based on F ω, will have nontrivial asymptotic local power against pure random effects. In fact, and analogous to ...

28 нояб. 2020 г. · Heteroskedastic robust F test is used to test if the overall model is significant or not. If the p-value F statistic is more than level of significance, then ...

It is used to test for heteroskedasticity in a linear regression model and assumes that the error terms are normally distributed.

We derive the asymptotic distribution of the standard F-test statistic for fixed effects, in static linear panel data models, under both non-normality and ...

The function bptest() in package lmtest does (the robust version of) the Breusch-Pagan test in R. The following code applies this function to the basic food ...

17 авг. 2020 г. · I know that (robust) R squared and F statistic from the "normal" model are still valid, but how do I get R to report them in the output?
