Hi everyone!
Im running the pooltest in plm package, like this
pooltest(cstfin12~lmaccdiscrz+lcobjur+lliq+lcollateral+ldimensao,
data = dados3,
model = "within")
But I got the following error:
Error in FUN(X[[1L]], ...) : insufficient number of
observations
My data is an unbalanced panel with 20907 observations
(6971 individuals and years 2001 to 2007). This is not
enough? Could anyone help me?
