st: How to test for equality of variance in data with sampling weights
Dear statalist users,
I am faced with a problem for which I have not been able to find a solution yet,
neither in statalist archives nor through googling, (even though it does not
strike me as something extremely fancy that I am trying)
I am working with household survey data, where the sample is not clustered, not
stratified, but has sampling weights. Ultimately, I would like to test the
equality of the variance of my labor wage variable
1) for the whole sample and for specific subgroups (such as age groups) over
2) for subgroups at the same point in time.
I am aware of the command "robvar" but
a) it does not feature weights
b) I am wondering if it is statistically appropriate to pool my data for two
years and specify 'year' as the groupvar in the by() option.
What would you advise me? Is there another command implemented?
Thank you very much in advance,
