quaray | R Documentation |
This function computes the quantiles of the Rayleigh distribution given parameters (\xi
and \alpha
) computed by parray
. The quantile function is
x(F) = \xi + \sqrt{-2\alpha^2\log(1-F)} \mbox{,}
where x(F)
is the quantile for nonexceedance probability F
, \xi
is a location parameter, and \alpha
is a scale parameter.
