invalid new variable name; . xtpmg d(co2pct drec ee gee) , lr(l.co2pct drec ee gee) ec(ECT) replace pmg unrecognized command: ml_model r(199); sir what can i do? i need your help
thank you sir I hope you will make us a video that explains how we can know the optimal offset and how to write in the pmg equation (e.g. offset (1 0 0 2 ) and good contuniation.
Hello sir Thank you this video really helps a lot . i have one question , can we use panel ARDL model if T=20 and N= 6 ? needed your help ! your suggestions are much appreciated
hello sir, ı will apply same as you but ı have problem invalid new variable name; variable name __ec is in the list of predictors what'is mean that? ı firstly calculated this code xtpmg d.toplammaliyet d.Coupled d.dcp d.trd d.othersub, lr(l.toplammaliyet Coupled dcp trd othersub) replace pmg after than ı use second code (7:09) xtpmg d.toplammaliyet d.Coupled d.dcp d.trd d.othersub, lr(l.toplammaliyet Coupled dcp trd othersub) replace mg
1/ what is d.g &l.g? (is 'g' variable in your dataset?) 2/ if PMG is selected as appropriate between PMG & MG, then will the next Hausman test be with PMG & DFE (unlike this video 12:04)?
hello, I can't declare the data of the panel especially from the heading times variables............ it displays on this side, the same thing as the other tab the term: year is not displayed on stata 16

hi sir kindly reply after this i got around 1567 iterations and not concave results what should i do next
what is meaning of 'not concave' in the iteration coloumn?
invalid new variable name;
. xtpmg d(co2pct drec ee gee) , lr(l.co2pct drec ee gee) ec(ECT) replace pmg
unrecognized command: ml_model
r(199);
sir what can i do? i need your help
what if all iterations are not concave???
thank you sir I hope you will make us a video that explains how we can know the optimal offset and how to write in the pmg equation (e.g. offset (1 0 0 2 ) and good contuniation.
I am working on it
@@econacademy16 hello sir i hope you are doing well, we really need a video that explains how we select optimal lags
thank you in advance
did u manage on this one@@mohamedaitelfakih2637
Hello sir Thank you this video really helps a lot . i have one question , can we use panel ARDL model if T=20 and N= 6 ? needed your help ! your suggestions are much appreciated
hello sir, ı will apply same as you but ı have problem
invalid new variable name;
variable name __ec is in the list of predictors
what'is mean that?
ı firstly calculated this code
xtpmg d.toplammaliyet d.Coupled d.dcp d.trd d.othersub, lr(l.toplammaliyet Coupled dcp trd othersub) replace pmg
after than ı use second code (7:09)
xtpmg d.toplammaliyet d.Coupled d.dcp d.trd d.othersub, lr(l.toplammaliyet Coupled dcp trd othersub) replace mg
i also face same issue, your problem is solved?
Could you solve the problem? Because i am having the same problem.
pmg is good but for mg(even after dropping)
invalid new variable name;
variable name __ec is in the list of predictors
r(110);
HELP
ı have same problem, are you found solutions
I also have the same problem and using Stata16 on Mac
Could you guys solve the problem? Because i am having the same problem.
Sir it is showing "could not calculate numerical derivatives flat or discontinuous region encountered"
1/ what is d.g &l.g? (is 'g' variable in your dataset?)
2/ if PMG is selected as appropriate between PMG & MG, then will the next Hausman test be with PMG & DFE (unlike this video 12:04)?
