Dear all,
i am replicating a paper so i know the results i should get; the aim is
to analyse the residual of a regression;
the problem is that when i regress the following:
glm lwage1 age educ educage educage2 educage3 educage4 [aw=hwt]
i obtain the same results as the author exept for the variance gap of
the 90-10 centile.
When instead i regress the following:
reg lwage1 age educ educage educage2 educage3 educage4 [aw=hwt]
i get the same 90-10 gap centile but the other results are different.
Both regressions give the same coefficient but the residual are
different:
Variable | Obs Mean Std. Dev. Min Max
------------+--------------------------------------------------------
resols | 1761676 -.0012382 .454438 -2.421267 3.340183
resglm | 1761676 1.77811 .3409537 .6651884 2.437594
Could you please suggest me what could be the problem or is it
methodologically not correct to work with the two regressions and
therefore with the two residuals?
Hope the problem is clear.
Best
Cinzia
