Dear statalist users,
I am running xtpmg on stata 16.0.
When I use the xtmpg, pmg option, my regression returns results. However, when I try to run a mg or dfe specification, I recieve an error message:
Maximum number of iterations exceeded.
r(498);
Any guidance on how to rectify this in order to run an mg or dfe specification would be appreciated.

Code:
xtpmg d.ew d.y d.y_sq , lr(l.ew y y_sq) replace pmg *This regression works xtpmg d.ew d.y d.y_sq , lr(l.ew y y_sq) replace dfe xtpmg d.ew d.y d.y_sq , lr(l.ew y y_sq) replace mg /*These regression don't work and give error message: Maximum number of iterations exceeded. r(498); */
