RE: st: Grouping income variables- RECODE COMMAND

If the graph is telling that the probability of missingnes is not
independent of the depression score. Clearly, we need to use imputation.
I have read here and there are different imputation methods

http://www.stata.com/support/faqs/statistics/clustering-and-mi-impute/

 I try to use strategy 1 but I am not sure about the Stata syntax to ımpute
the values of household income. 

Should I use the strategy 3 ? I am not familiar with these methods. Can you
give me any clue?

Say, union in my example is wage in yours and grade in my example is
depression in yours.

*------------------ begin example ------------------ sysuse nlsw88, clear
gen byte miss = missing(union)

logit miss grade
predict pr

logit mis i.grade
testparm i.grade

collapse (mean) miss pr, by(grade)

twoway line miss pr grade
*------------------- end example -------------------
* (For more on examples I sent to the Statalist see:

Hope this helps,
