st: AW: modl and modltbl after svy: regress

["Martin Weiss" <martin.weiss1@gmx.de>]

<> 

The command seems to date back all the way to August 1997 and is accessible
via -findit modl-. It sets -version 5.0-, so you may want to get its modern
incarnations -ssc d estout- or -ssc d outreg2-.

Betreff: st: modl and modltbl after svy: regress

Hello,

I would like to use the modl and modltbl commands after svy: regress.  I 
do the following:

svy, subpop($subpop): regress $wage
modl 1

The response is:
. modl 1
Last estimates not found.
modl must immediately follow an estimation procedure.
r(301);

However, if I look at last estimates, I get:

. ereturn list

scalars:
                 e(r2) =  0
             e(stages) =  1
              e(N_sub) =  377278
           e(N_subpop) =  4.579482189141677
                  e(N) =  683840
              e(N_pop) =  7.878162752876319
           e(N_strata) =  28
              e(N_psu) =  402352
               e(df_r) =  402324
      e(N_strata_omit) =  0
          e(singleton) =  0
             e(census) =  0
               e(k_eq) =  1
               e(df_m) =  0
               e(rank) =  1

macros:
                e(cmd) : "regress"
            e(cmdline) : "svy , subpop(employee): regress lnnetmwdp"
             e(prefix) : "svy"
            e(cmdname) : "regress"
            e(command) : "regress lnnetmwdp"
          e(estat_cmd) : "svy_estat"
                e(vce) : "linearized"
            e(vcetype) : "Linearized"
              e(title) : "Survey: Linear regression"
             e(subpop) : "employee"
               e(wexp) : "= nw1"
              e(wtype) : "pweight"
               e(wvar) : "nw1"
         e(singleunit) : "missing"
                e(su1) : "casenum"
            e(strata1) : "cid"
         e(properties) : "b V"
          e(marginsok) : "XB default"
             e(depvar) : "lnnetmwdp"
            e(predict) : "regres_p"
              e(model) : "ols"

matrices:
                  e(b) :  1 x 1
                  e(V) :  1 x 1
       e(V_modelbased) :  1 x 1
           e(V_srssub) :  1 x 1
              e(V_srs) :  1 x 1
  e(_N_strata_certain) :  1 x 1
   e(_N_strata_single) :  1 x 1
          e(_N_strata) :  1 x 1

functions:
             e(sample)

and:
. mat list e(b)

symmetric e(b)[1,1]
      _cons
y1  .839104

So the last estimates do exist.

When I rerun the same command using just regress (regress $wage [w=nw1] 
if $subpop), the "modl 1" command works.

Can anyone tell me why modl is not recognizing the last estimates for 
svy: regress and/or how to fix this?

Thank you,
Helen Connolly
