Geometric Distribution Functions

Source: R/geometric_distribution.R
geometric_distribution.Rd

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

Usage

geometric_pdf(x, prob)

geometric_lpdf(x, prob)

geometric_cdf(x, prob)

geometric_lcdf(x, prob)

geometric_quantile(p, prob)

Arguments

x

quantile (non-negative integer)

prob

probability of success (0 < prob < 1)

p

probability (0 <= p <= 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.
