Hi, Berton: thanks for getting back to me. I played around cor.rob(). Yes, I can get a robust correlation coefficient matrix based on mcd or mve outlier detection methods. I have two further questions: 1) How do I get a p value of the robust r? 2) What I mean by resampling is "leave one out"

Hi, there: As you all know, correlation is not a very robust procedure. Sometimes correlation could be driven by a few outliers. There are a few ways to improve the robustness of correlation (pearson correlation), either by outlier removal procedure, or resampling technique. I am wondering i
