| 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.
