{title:Description}

{pstd}
{cmd:xtregkv} fits random effects gls-models with unit-specific mean variables ("Hybrid Models"). For each specified independent variable of the model, the unit-mean of that variable is also integrated. Thus {cmd:xtregkv} reproduces the results of a fixed effects-regression for time-dependant variables, but also allows for the estimation of 
time-invariant variables.
