Hi,
In examining the correlation between two variables, what is the difference in utility of the Spearman correlation co-efficient (stata command 'spearman') and the Pearson correlation co-efficient (stata command "pwcorr" or "correlate")?
Is there a situation where one is more applicable than the other? What does it mean if the correlation is significant with one but not the other?
Thanks,
Ashwin
