merMod-class: Class "merMod" of Fitted Mixed-Effect Models

Description

A mixed-effects model is represented as a merPredD object and a response module of a class that inherits from class lmResp. A model with a lmerResp response has class lmerMod; a glmResp response has class glmerMod; and a nlsResp response has class nlmerMod.

Usage

## S3 method for class 'merMod':
vcov(object, correlation = TRUE, sigm = sigma(object), ...)

Arguments

object

an Robject of class merMod, i.e., as resulting from lmer(), or glmer(), etc.

correlation

logical indicating if the correlation matrix is desired in addition to the variance covariance one.

sigm

the residual standard error; by default sigma(object).

...

potentially further arguments pass from other methods.

Objects from the Class

Objects are created by calls to lmer, glmer or nlmer.
