dneymanA: The Neyman-A probability function

In jointNmix: Joint N-Mixture Models for Site-Associated Species

Description

Computes the probability function of the Neyman-A distribution

Usage

dneymanA(x, lambda1, lambda2, K, log = FALSE)

Arguments

x	vector of values
lambda1, lambda2	parameters of the distribution
K	truncation value for the infinite summation
log	logical. If TRUE, the logarithm of the probabilities is returned

Details

The Neyman-A distribution has probability function

\frac{e^{-λ_1}λ_2^{x}}{x!}∑_{k=0}^∞\frac{(λ_1e^{-λ_2})^kk^x}{k!}

and is an overdispersion model. The summation is truncated to K.
