MEestimate: Estimate mixed-effects parameters

Description

Estimate the parameters in a linear mixed-effects model.

Usage

MEestimate(object, groups, conLin=attr(object, "conLin"))

Arguments

object
an object that inherits from class lmeStruct, describing a linear mixed-effects model or a nonlinear mixed-effects model.
groups
a factor or list of factors giving the grouping of the observations
conLin
a condensed linear model object. The default is attr(object, "conLin").

Value

  • A list with components
  • logLikthe log-likelihood at the estimate.
  • bthe estimated BLUP's (Best Linear Unbiased Predictors) of the random effects
  • betathe estimates of the fixed effects
  • sigmathe estimated standard deviation of the within-subject noise term.
  • varFixthe estimated variance-covariance matrix of the fixed effects
