cdfray {lmomco} | R Documentation |
This function computes the cumulative probability or nonexceedance probability
of the Rayleigh distribution given parameters (xi and α) of the distribution computed
by parray
. The cumulative distribution function of the distribution is
F(x) = 1 - e^{-(x - xi)^2/(2α^2)}mbox{,}
where F(x) is the nonexceedance probability for quantile x, xi is a location parameter, and α is a scale parameter.
