extract.lmeDesign: Extract the Design of a linear mixed model

Description

These functions extract various elements of the design of a fitted lme-, mer or lmerMod-Object. They are called by exactRLRT and exactLRT.

Usage

extract.lmeDesign(m)
extract.lmerDesign(m)
extract.lmerModDesign(m)

Arguments

m

fitted lme- or mer-Object

Value

• a list with components
• Vr
  estimated covariance of the random effects divided by the estimated variance of the residuals
• X
  design of the fixed effects
• Z
  design of the random effects
• sigmasq
  variance of the residuals
• lambda
  ratios of the variances of the random effects and the variance of the residuals
• y
  response variable

Examples

library(nlme)
d <- extract.lmeDesign(lme(distance ~ age + Sex, data = Orthodont, random = ~ 1))
