residualsAcat: This is a function to deal with the vglm object in S4.

Description

This is a function to deal with the vglm object in S4.

Usage

residualsAcat(
  object,
  type = c("surrogate", "sign", "general", "deviance"),
  jitter = c("latent", "uniform"),
  jitter.uniform.scale = c("probability", "response"),
  nsim = 1L,
  ...
)

Arguments

object

An object of class vglm.

type

The type of residuals which should be returned. The alternatives are: "surrogate" (default), "sign", "general", and "deviance". Can be abbreviated.

surrogate

surrogate residuals (Liu and Zhang, 2017);

sign

sign-based residuals;

general

generalized residuals (Franses and Paap, 2001);

deviance

deviance residuals (-2*loglik).

jitter

A character string specifying which method to use to generate the surrogate response values. Current options are "latent" and "uniform". Default is "latent".

latent

latent approach;

uniform

jittering uniform approach.

jitter.uniform.scale

A character string specifying the scale on which to perform the jittering whenever jitter = "uniform". Current options are "response" and "probability". Default is "response".

nsim

An integer specifying the number of replicates to use. Default is 1L meaning one simulation only of residuals.

...

Additional optional arguments.

Value

A "resid" object with attributes. It contains a vector or a matrix (nsim>1) of residuals for the adjacent categories model.
