pdfray {lmomco} | R Documentation |
This function computes the probability density
of the Rayleigh distribution given parameters (xi and α) of the distribution computed
by parray
. The probability density function of the distribution is
f(x) = frac{x - xi}{α^2}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.
