...V = 1819, p-value = 0.8812.   Then I calculated the z-value of the test: z-value = -2.661263. The corresponding p-value is: p-value = 0.003892, which is different from the p-value computed in the Wilcox test, I am using the following steps to compute the z-value:   diff = c(endprice0 - endprice1) diffNew = diff[diff !=0] diffNew.rank = rank(abs(diffNew)) diffNew.rank.sign <-  diffNew.rank  *  sign(diffNew) ranks.pos <- sum(diffNew.rank.sign[diffNew.rank.sign >0]) = 1819 ranks.neg <- -sum(diffNew.rank.sign[diffNew.rank.sign<0]) = 1751   v = ranks.neg n = 100 z= (v - n *(n+1)/4)/sqrt(n...

Hi! Thanks for this service! It is very helpful to know what is being developed. I distribute the content to other venues and I noticed some times that the updates are duplicated. For example, the sentence "?is.R()? is deprecated as no other S dialect is known to be in use (and this could only identify historical dialects, not future ones)." is duplicated in different days: Day 1:
