- I am trying to do Panel group mean DOLS with 6 panels (countries) each one has 25 observations including: log(GDP per capita) log(labor force) log(gross capital per capita) log(renewable consumption) log(imports or exports)
- When I do the test for four variables:
xtpedroni ly lk ll lrec
everything works fine. but when I apply all variables
xtpedroni ly lk ll lrec lim
I got this error:
matrix not positive definite
r(506);
What do you think the problem is?
