weibull_distribution: Weibull Distribution Functions

Description

Functions to compute the probability density function, cumulative distribution function, and quantile function for the Weibull distribution.

Usage

weibull_pdf(x, shape = 1, scale = 1)
weibull_lpdf(x, shape = 1, scale = 1)
weibull_cdf(x, shape = 1, scale = 1)
weibull_lcdf(x, shape = 1, scale = 1)
weibull_quantile(p, shape = 1, scale = 1)

Value

A single numeric value with the computed probability density, log-probability density, cumulative distribution, log-cumulative distribution, or quantile depending on the function called.

Arguments

x

quantile

shape

shape parameter (default is 1)

scale

scale parameter (default is 1)

p

probability (0 <= p <= 1)
