I'm using the IPUMS provided CPS data (ASEC) and am running a wage regression. Basically, I do
which is basically regressing log wages onto a particulary industry code by year. However, I get the following output:
SDR replications (160)
----+--- 1 ---+--- 2 ---+--- 3 ---+--- 4 ---+--- 5
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 50
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 100
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 150
xxxxxxxxxx
insufficient observations to compute bootstrap standard errors
no results will be saved
What should I do?
Code:
svyset [iw=wtsupp], sdrweight(repwt1-repwt160) vce(sdr) replace incwage = . if incwage == 9999999 replace incwage = . if incwage == 9999998 gen wage_log = log(incwage) drop if year < 2000 gen food = ind1990 == 641 gen food_year = food * year svy: reg wage_log I.food_year
