ll {estimators}

Log-Likelihood

Description

These functions calculate the log-likelihood of an IID sample for specific values of the distribution parameters. See Details.

Usage

ll(x, prm, distr, ...)

Arguments

x

numeric. A sample under estimation.

prm

numeric. A vector of the distribution parameters.

distr

A subclass of Distribution. The distribution family assumed.

...

extra arguments.

location, alpha, mu, sigma, meanlog, sdlog, min, max, size, prob, shape, rate, scale, mean, sd, lambda

numeric. Distribution parameters.

Details

The log-likelihood functions are provided in two forms: the ⁠ll<name>⁠ distribution-specific version that follows the base R conventions, and the S4 generic ll.

Value

Numeric. The value of the log-likelihood function.
