Dear Sven:
Please, find attached the .xlsx dataset for replication purposes.
As far I know, there are not missing values in this dataset.
OK thanks. I don't have the time to take a very close look, but I'm
noticing that doing:
dpanel 1 ; Afiliados Coast Aerop70 Walk Pmain Dens DPrs_2
(i.e. without --system --dpdstyle, replacing DPrs11_2 with DPrs_2, and
dropping 0 [although the latter doesn't matter])
yields a matrix non-pos-def error. This may suggest that some dropping
_maybe_ should be done somewhere.
cheers
