And why is this a problem? The cdf of an exponential distribution with rate = 0.5 evaluated at x = 50 is very close to 1. If you want to find out exactly how close you could use pexp(50, rate = 0.5, lower.tail = FALSE) which gives an answer on the order of 10^(-11). ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
