Although in correlation the n-1 cancel out, statistical stddev and cov should use sample variance, as the estimated mean is used in E(X-E(X))^2 is one less degree of freedom.
I am rather dubious of any context where that's a significant issue. Anyways, if I had really wanted to represent traditional standard deviation, I'd used STDDEV as a name, rather than SD. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
