Amen! In fact, tests on Spearman coefficients are notoriously sensitive to normality. An article by Egon Pearson in Biometrika in the 1970s showed this clearly.

Otherwise P-values for correlations are over-rated in my view, whether in -svy- contexts or otherwise. Others should have comments on the -svy- aspects.

As I understand, I can calculate Pearson correlations using corr with aweight for the coefficients and then calculate the p-values using svy: regress y x and svy: regress x y then selecting the larger p-value. Is there a way of calculating Spearman correlations using a survey weight and bootstrap weights?* * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/ * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/faqs/resources/statalist-faq/ * http://www.ats.ucla.edu/stat/stata/
