weighted correlations using svyset and svy

[Jenn Finders]

Hi Statalisters,

I am hoping to get weighted correlations and the appropriate p-values using survey data. I have tried the -corr_svy- command and the correlations do not appear to differ from the correlations using the -corr- command which does not account for weighting and sampling design. I have read that it may not be possible to get obtain weighted correlations with Stata 14 (https://stats.idre.ucla.edu/stata/seminars/survey-data-analysis-with-stata-14/)but any help regarding a workaround is appreciated.

svyset [pweight= W7C17P_20], jkrweight(W7C17P_21-W7C17P_240) vce(jack) mse
corr_svy

Thanks!

corr_svy is an old command written by Nick Winters in 2001 A look at the ado file ("viewsource corr_svy.ado") shows that it was written for Stata 7, which had very different syntax for svyset. The solution is run your do file under version control and use the old svyset syntax, some of which I found here :

sysuse auto, clear
version 7
svyset psu rep78
svyset pweight length
corr_svy mpg weight length

Hmm. I doubt that svyset in Stata 7 accepted replicate weights, so this won't work. Sorry.

A bit out of date, but look at the solution Statacorp gave to this issue back in 2014 (posting in case this comes up for anyone else googling this issue).
