Hello. I sent an Email in r-help without answer for the moment. I am wondering if it could have a mistake in the code of the ansari.test function. For me, it seems that the function do not recover the p value at the correct side of the normal law N(0, 1) when it use the normal approximation (presence of ties) in a one tailed test. Here is what is written in ansari.test : p <- pnorm(normalize(STATISTIC, r, TIES)) PVAL <- switch(alternative, two.sided = 2 * min(p, 1 - p), less = 1 - p, greater = p) pnorm() is written without "lowertail = FALSE". So it should be : less = p greater = 1-p Am I wrong ??? Thanks very much for your help. Gael.
