likgamma: Gamma Log Likelihood Function

In likelihoodExplore: Likelihood Exploration

Description

The log likelihood of a gamma density with data, x, shape, rate and scale parameters.

Usage

likgamma(x, shape, rate = 1, scale = 1/rate, log = TRUE)

Arguments

x	vector of quantiles.
shape	shape and scale parameters. Must be positive, scale strictly.
rate	an alternative way to specify the scale.
scale	shape and scale parameters. Must be positive, scale strictly.
log	logical; if TRUE, probabilities/densities p are returned as log(p).

Details

The log likelihood is the log of a function of parameters given the data.

Value

A numeric scalar for the log likelihood of the gamma density given the data where shape, scale, and rate can be held constant or if vector were given vector will be returned.

Examples

likgamma(x = rgamma(n = 2, shape = 3),
        shape = 3)
