# st: Svyselmlog / Predict Values

 From Ana To statalist@hsphsun2.harvard.edu Subject st: Svyselmlog / Predict Values Date Wed, 11 Jul 2012 13:40:16 -0300

```Dear Stata users,

I am trying to estimate the wage equations of public and private
sector, while considering the selection that involves the choice of
non-working versus working at public sector versus working at private
sector. I’m following the Bourguignon, Fournier and Gurgand (2004)
model. I’m using the svyselmlog routine (‘selectivity-adjusted
equation based in the multinomial logit for survey data’).

I need to have the predict values of both wage equations (predicted
public sector wage and predicted private wage). And that is the
problem I am facing: I can´t get my predicted values (based on all
regressors,  the dependent variables and  the inverse mills ratio as
well).

Here is the routine:

gen cons = 1
#d ;
svyselmlog lnwhpad exp exp2 fundamental medio superior branco female
NORTE CENTOES SE SUL,select(setgeral exp exp2 fundamental medio
superior branco female NORTE CENTOES SE SUL chefe allincsources filho
#d cr
**************
*************
mkmat   exp exp2 fundamental medio superior branco female NORTE
CENTOES SE SUL dmfhpad* cons, matrix(var_rhs)
*************

**************
mkmat   exp exp2 fundamental medio superior branco female NORTE
CENTOES SE SUL dmfhpad* cons, matrix(var_rhs)
r(111);
*************

Can anyone help me?
Best regards,
Ana.
