Hi Everybody,


I am running a regression analysis using HLFS on Stata. I have been told that I need to use sample weights to have reliable estimates. The HLFS data has a "factor weight" column for each observation. My questions are as follows:


1) Does it mean that HLFS data already provide me with the sample weights? So, I don't need to calculate it?

2) If the answer is yes to (1), how do I use this on Stata?

I am writing a command as below, but I am not quite sure if I am weighting twice. [pweight=weights] --> The bold represents the factor weight column on HLFS data.

oaxaca LnWage var1 var2 var3 var4 var5 [pweight=weights], by(Gender) pooled

3) If answer to (1) is no, then how can I calculate the sample weights, as I don't know the total population of a sector?



Any suggestion would be much appreciated!

Thank you very much for your time and effort.
