How can we actually compute the p-value for the Hansen-Jagannathan distance (1996)?I don't find the methodology very well explained in Jagannathan and Wang (1996).Did anybody implement it?Thanks,David
HJ-distance is a GMM-based test used in CAPM to check whether all the alphas are zero. It's an alternative to Hansen J test, documented by Cochrane in "Asset pricing".If you don't use that, what do you use?
