Gamma Count {rmutil} R Documentation

## Gamma Count Distribution

### Description

These functions provide information about the gamma count distribution with parameters m and s: density, cumulative distribution, quantiles, and random generation.

The gamma count distribution with prob = m has density

p(y) = pgamma(m s, y s, 1)-pgamma(m s, (y+1) s, 1)

for y = 0, ..., n where pgamma(m s, 0, 1)=1.

### Usage

dgammacount(y, m, s, log=FALSE)
pgammacount(q, m, s)
qgammacount(p, m, s)
rgammacount(n, m, s)

### Arguments

 y vector of frequencies q vector of quantiles p vector of probabilities n number of values to generate m vector of probabilities s vector of overdispersion parameters log if TRUE, log probabilities are supplied.
