weib: The Weibull distribution, for binary regression

In dnzmarcio/binreg: binreg R package

Description

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

Usage

 dweib(x, gamma)
 pweib(q, gamma)
 qweib(p, gamma)
 rweib(n, gamma)

Arguments

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

Details

The 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

'dweib' gives the density, 'pweib' gives the distribution function, 'qweib' gives the quantile function, and 'rweib' generates random deviates.
