WebbIf you want the exact cdf of a Gaussian, the function you are looking for is pnorm (). Here is a demonstration. x <- seq (from=-5, to=5, by=.1) y <- pnorm (x) plot (x, y, type='l') If you replace dnorm () by pnorm () in your code, and x by the range of values you want to take the cdf over you should get the result you are looking for. Share Cite WebbOne way to do that is to find the exponential distribution whose cumulative distribution function (CDF) best approximates (in a sense to be explained below) the ECDF of the data. The exponential CDF is p = Pr {X <= x} = 1 - exp (-x/mu). Transforming that to -log (1-p)*mu = x gives a linear relationship between -log (1-p) and x.
