WebWhen n is odd or n > 1000, the median is kth element k = (n + 1) / 2. when n is even and n < 1000the median is a mean of the elements k = n/2 and k = n/2 + 1. If the weights are supplied (w not 0) all weights must be >= 0. If work is supplied, it is used to store the sorting index and assumed to be >= n .

WebDescription TMath::Poisson (n,mu) for n = 0 and mu < 0 returns wrong value , instead of returning a NaN it returns exp (-mu) which is completely wrong.
