margins after ppmlhdfe

[Eran Itskovich]

Hi all,

I'm running a poisson fixed-effects model using -ppmlhdfe- :

ppmlhdfe dep_var i.indep_var1..., a(i.panel i. time) vce(cluster i.panel) d

This model runs just fine, but then I'm trying to run -margins- :

margins i.indep_var1, atmeans

and I get this error:

variable __00001A not found
               st_data():  3598  Stata returned error
        __marg_cr_eval():     -  function returned error
    deriv__call2user_v():     -  function returned error
 _deriv__compute_value():     -  function returned error
                _deriv():     -  function returned error
   st__marg_cr_compute():     -  function returned error
                 <istmt>:     -  function returned error

I've noticed that it only happens when I use the -atmeans- option. When I don't, it works fine.
Does anyone know why I get this error?

Thanks!
Eran

Hi Eran,

I am facing the same problem. May I ask whether you got the solution?

Thanks!,
