logistic_distribution: Logistic Distribution Functions

Description

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

Usage

logistic_distribution(location = 0, scale = 1)
logistic_pdf(x, location = 0, scale = 1)
logistic_lpdf(x, location = 0, scale = 1)
logistic_cdf(x, location = 0, scale = 1)
logistic_lcdf(x, location = 0, scale = 1)
logistic_quantile(p, location = 0, 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

location

location parameter (default is 0)

scale

scale parameter (default is 1)

x

quantile

p

probability (0 <= p <= 1)
