pdfsla | R Documentation |
This function computes the probability density of the Slash distribution given parameters (\xi
and \alpha
) provided by parsla
. The probability density function is
f(x) = \frac{\phi(0) - \phi(y)}{y^2} \mbox{,}
where f(x)
is the probability density for quantile x
, y = (x - \xi)/\alpha
, \xi
is a location parameter, and \alpha
is a scale parameter. The function \phi(y)
is the probability density function of the Standard Normal distribution.
