residuals.izip: Extract iZIP Model Residuals

In thomas-fung/izipr: Interpretable Zero-Inflated Poisson Models in R

Description

residuals is a generic function which extracts model residuals from objects returned by the modelling function glm.izip or tsglm.izip. resid is an alias for residuals .

Usage

## S3 method for class 'izip'
residuals(object, type = c("deviance", "pearson", "response"), ...)

## S3 method for class 'tsizip'
residuals(object, type = c("response", "pearson"), ...)

Arguments

object	an object class 'izip' or 'tsizip', obtained from a call to glm.izip or tsglm.izip.
type	the type of residuals which should be returned. The alternatives are: 'deviance' (default), 'pearson' and 'response' for an 'izip' object; 'response' (default), and 'pearson' for an 'tsizip' object. Can be abbreviated.
...	other arguments passed to or from other methods (currently unused).

Value

Residuals extracted from the object object.

Examples

data(bioChemists)
M_bioChem <- glm.izip(art ~ ., data = bioChemists)
# deviance residuals
residuals(M_bioChem)

data(arson)
M_arson <- tsglm.izip(arson ~ 1, past_mean_lags = 1, past_obs_lags = c(1, 2))
# pearson residuals
resid(M_arson, type = "pearson")
