Issue with estadd mlogtest, combine

[Diego Gomes]

Hello,

I'm trying to use the command estadd mlogtest, combine in order to export the results to a LaTeX table. However, an error message appears after running it. Here is an example:

. webuse nhanes2f, clear

. quietly svy: mlogit health weight height i.female

. estadd mlogtest, combine

Wald tests for combining alternatives (N=10335)

  Ho: All coefficients except intercepts associated with a given pair
      of alternatives are 0 (i.e., alternatives can be combined)

                 |         F    df   df_r      P>F

added scalars:

end of do-file

The problem doesn't happen when using other options of the mlogtest. Here is an example using the wald option:

. webuse nhanes2f, clear

. quietly svy: mlogit health weight height i.female

. estadd mlogtest, wald

Wald tests for independent variables (N=10335)

  Ho: All coefficients associated with given variable(s) are 0

                 |         F    df   df_r      P>F
-----------------+--------------------------------
          weight |    23.317     4      4    0.000
          height |    53.000     4      4    0.000
        1.female |    10.297     4      4    0.000

added matrices:
               e(wald) :  4 x 3      (F, df, df_r, P>F)

.
end of do-file

Note that the version of the mlogtest I'm using is:

. which mlogtest

/Users/diegogomes/Library/Application Support/Stata/ado/plus/m/mlogtest.ado
*! version 3.5.0 2016-10-25 | long freese | problem in Stata 14.2 smhsiao

Does anyone know what is happening? Is there a workaround?

Thanks!
