Faddyprob.general: Calculation of vector of probabilities for a Faddy...

In CountsEPPM: Mean and Variance Modeling of Count Data

Description

Given a vector of parameters and a scalar of the maximum count the function calculates the vector of lambdas for a Faddy distribution and returns a vector of probabilities.

Usage

Faddyprob.general(parameter, nmax)

Arguments

parameter	A vector of the parameters of the Faddy distribution.
nmax	The value of the maximum count.

Value

Vector of probabilities
