Zero-Inflated Gamma-Poisson Residuals

Zero-Inflated Gamma-Poisson Residuals

Usage

res_gamma_pois_zi(
  x,
  lambda = 1,
  theta = 0,
  prob = 0,
  type = "dev",
  simulate = 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 zero-inflation.

type

A string of the residual type. 'raw' for raw residuals 'dev' for deviance residuals and 'data' for the data.

simulate

A flag specifying whether to simulate residuals.

Value

An numeric vector of the corresponding residuals.
