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
• logLik
  the log-likelihood at the estimate.
• b
  the estimated BLUP's (Best Linear Unbiased Predictors) of the random effects
• beta
  the estimates of the fixed effects
• sigma
  the estimated standard deviation of the within-subject noise term.
• varFix
  the estimated variance-covariance matrix of the fixed effects
