I want to ask you the following question about Stata 15:

- The data matrix I manage has almost 200,000 observations

- I estimate a multilevel ordinal logit, with 8 integration points. The estimate takes me 2 hours on my computer.

- I save the estimate and ask for the average marginal effect of all the exogenous variables through the following instruction:

margins, dydx (c_sexo_r c_edad c_casado_pareja c_educacion_primaria c_educacion_secundaria c_educacion_superior c_desempleado c_salud_7 c_religion c_indigena c_junta_vecinos c_numper c_p_1_10_lrenta__f_e_d_f_ec

after more than 12 hours I don't get results, when the estimate converges around 2 hours

1.- What can it be due to?

2.- Give me some clue to get the result.

Thank you
