Hello Cecilia, nice hearing from you again. I must restate a couple of my old hints, though ;^) 1) please always put the authors c/c, as we are not guaranteed to browse through the r-help every day 2) please provide reproducible examples.
As example(pooltest) keeps working fine, as do some other cases I tried (Grunfeld data etc.), I don't know what the problem is but evidently your data are peculiar in exposing it. Sure the data numerosity must be enough, but maybe you have something which doesn't vary along some dimension, and gets dropped? or some groups which are all-NA? Do the "random" and "pooling" options crash as well? You might use traceback() to better identify the problem, and/or send a complete example to the list or even to me separately if it's too heavy.

I?m 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).
