cdflap | R Documentation |
This function computes the cumulative probability or nonexceedance probability of the Laplace distribution given parameters (\xi
and \alpha
) computed by parlap
. The cumulative distribution function is
F(x) = \frac{1}{2} \mathrm{exp}((x-\xi)/\alpha) \mbox{ for } x \le \xi \mbox{,}
and
F(x) = 1 - \frac{1}{2} \mathrm{exp}(-(x-\xi)/\alpha) \mbox{ for } x > \xi \mbox{,}
where F(x)
is the nonexceedance probability for quantile x
,
\xi
is a location parameter, and \alpha
is a scale parameter.
