Hi all,
I have tried to compute a p-value for a hypergeometric distribution as:
dhyper(x,k,l,n) + phyper(x,k,l,n,lower.tail=FALSE)
and sometimes obtained negative values. Do you know if it is because a round error or am I doing something wrong?
Could you give us specific x,k,l,n where this happens, please. It sounds like it shouldn't happen.
