dpareto.ll: Maximum Likelihood Estimation for the Discrete Pareto Distribution

Description

Performs maximum likelihood estimation for the parameter of the discrete Pareto distribution.

Usage

dpareto.ll(x, theta = NULL, ...)

Arguments

x

A vector of raw data which is distributed according to a Poisson-Lindley distribution.

theta

Optional starting value for the parameter. If NULL, then the method of moments estimator is used.

...

Additional arguments passed to the mle function.

Value

See the help file for mle to see how the output is structured.

Details

The discrete Pareto distribution is a discretized of the continuous Type II Pareto distribution (also called the Lomax distribution).
