cweib: The Reflected Weibull distribution, for binary regression

In dnzmarcio/binreg: binreg R package

Description

Density, distribution function, quantile function and random generation function for the Reflected Weibull distribution with one parameter.

Usage

 dcweib(x, gamma)
 pcweib(q, gamma)
 qcweib(p, gamma)
 rcweib(n, gamma)

Arguments

x, q	vector of quantiles.
p	vector of probabilities.
n	number of observations.
gamma	shape parameter.

Details

The Reflected Weibull distribution with parameter gamma has density given by

f(x) = gamma*((-x)^(gamma - 1))*exp(-x^gamma)

for x < 0 and gamma > 0.

Value

'dcweib' gives the density, 'pcweib' gives the distribution function, 'qcweib' gives the quantile function, and 'rcweib' generates random deviates.
