Zero-Inflated Gamma-Poisson Deviances

Zero-Inflated Gamma-Poisson Deviances

Usage

dev_gamma_pois_zi(x, lambda = 1, theta = 0, prob = 0, res = FALSE)

Arguments

x

A non-negative whole numeric vector of values.

lambda

A non-negative numeric vector of means.

theta

A non-negative numeric vector of the dispersion for the mixture models (student, gamma-Poisson and beta-binomial).

prob

A numeric vector of values between 0 and 1 of the probability of success.

res

A flag specifying whether to return the deviance residual as opposed to the deviance.

Value

An numeric vector of the corresponding deviances or deviance residuals.

Examples

dev_gamma_pois_zi(c(1, 3, 4), 3, 2)
