dpn: The PN distribution

Description

Density, distribution function, quantile function and random generation for the PN distribution with power equal to alpha.

Usage

dpn(x, alpha)
ppn(q, alpha)
qpn(p, alpha)
rpn(n, alpha)

Arguments

x, q

vector of observations or quantiles.

p

vector of probabilities.

n

number of observations.

alpha

power parameter.

Details

The alpha parameter must be greater than 0 (alpha > 0).
