Exactness of ppois
Hello, by checking the precision of a convolution algorithm, we found the following "inexactness": We work with R Version 1.8.1 (2003-11-21) on Windows systems (NT, 2000, XP). Try the code: ## Kolmogorov distance between two methods to ## determine P(Poisson(lambda)<=x) Kolm.dist <- function(lam, eps){ x <- seq(0,qpois(1-eps, lambda=lam), by=1) max(abs(ppois(x, lambda=lam)-cumsum(dpois(x, lambda=lam)))) } erg<-optimize(Kolm.dist, lower=900, upper=1000, maximum=TRUE, eps=1e-15)...
