MEestimate {nlme} | R Documentation |
Estimate the parameters in a linear mixed-effects model.
MEestimate(object, groups, conLin=attr(object, "conLin"))
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") . |
This is a utility function used by lme
and nlme
. It is
not intended for direct use.
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 |
