Conformability error in gidm command

[Maria Clemente]

Hello everyone,

I have been trying to use the regression command GIDM and this error keeps appearing every time I add one new variable to the inflation part of the model.

In the following table, you can find the description of the variables I use:

  Variable |        Obs        Mean    Std. dev.       Min        Max
-------------+---------------------------------------------------------
         d_i |     21,889     .128375    .4305402          0          4
N_retirincap |     21,889     .512769    .8369079          0         10
        area |     21,889    .7785189    .4152531          0          1
    nadultos |     21,889    2.084289    .9797261          1         12
    nmenores |     21,889     .325506    .7024319          0          9
-------------+---------------------------------------------------------
      income |     21,766    2.612607    1.377871          1          5
      h_educ |     21,889    1.824432    .9126781          0          3
        CCAA |     21,889    8.915209    5.012314          1         19
health_per~n |     21,889    2.182923    .9065323          1          5

then the command for the regression is:

gidm (d_i N_retirincap area nadultos nmenores i.income i.h_educ ib13.CCAA) (i.health_perception) (i.health_perception) (i.health_perception) (i.health_perception) [fw=fwt], inflation(0 1 2 3) link(lgcl)

However, when I chage it to:

gidm (d_i N_retirincap area nadultos nmenores i.income i.h_educ ib13.CCAA) (i.health_perception nmenores) (i.health_perception nmenores) (i.health_perception nmenores) (i.health_perception nmenores) [fw=fwt], inflation(0 1 2 3) link(lgcl)

This error comes out:

        *:  3200  conformability error
          opt__cns_off():     -  function returned error
opt__looputil_iter0_common():     -  function returned error
opt__looputil_iter0_nr():     -  function returned error
          opt__loop_nr():     -  function returned error
             opt__loop():     -  function returned error
            _moptimize():     -  function returned error
           Mopt_maxmin():     -  function returned error
                 <istmt>:     -  function returned error
r(3200)        *:  3200  conformability error
          opt__cns_off():     -  function returned error
opt__looputil_iter0_common():     -  function returned error
opt__looputil_iter0_nr():     -  function returned error
          opt__loop_nr():     -  function returned error
             opt__loop():     -  function returned error
            _moptimize():     -  function returned error
           Mopt_maxmin():     -  function returned error
                 <istmt>:     -  function returned error
r(3200);

I know what it means and I have tried replacing the error as recommended in other posts. However, in this case, it does not work, do you know why could be the reason?

I appreciate any help you can provide.
