residuals.merMod: residuals of merMod objects

Description

residuals of merMod objects

Usage

## S3 method for class 'merMod':
residuals(object,
    type = if (isGLMM(object)) "deviance" else "response",
    scaled = FALSE, ...)
  ## S3 method for class 'lmResp':
residuals(object,
    type = c("working", "response", "deviance", "pearson", "partial"),
    ...)
  ## S3 method for class 'glmResp':
residuals(object,
    type = c("deviance", "pearson", "working", "response", "partial"),
    ...)

Arguments

object

a fitted [g]lmer (merMod) object

type

type of residuals

scaled

scale residuals by residual standard deviation (=scale parameter)?

...

additional arguments (ignored: for method compatibility)

Details

• The default residual type varies betweenlmerModandglmerModobjects: they try to mimicresiduals.lmandresiduals.glmrespectively. In particular, the defaulttypeis"response", i.e. (observed-fitted) forlmerModobjects vs."deviance"forglmerModobjects.type="partial"is not yet implemented for either type.
• Note that the meaning of"pearson"residuals differs betweenresiduals.lmandresiduals.lme. The former returns values scaled by the square root of user-specified weights (if any), butnotby the residual standard deviation, while the latter returns values scaled by the estimated standard deviation (which will include the effects of any variance structure specified in theweightsargument). To replicatelmebehaviour, usetype="pearson",scaled=TRUE.
