refitML function

Refit a Model by Maximum Likelihood Criterion

Refit a (merMod) model using the maximum likelihood criterion.

refitML(x, ...)
## S3 method for class 'merMod'
 refitML(x, optimizer = "bobyqa", ...)

Arguments

• x: a fitted model, usually of class "lmerMod", to be refit according to the maximum likelihood criterion.
• ...: optional additional parameters. None are used at present.
• optimizer: a string indicating the optimizer to be used.

Returns

an object like x but fit by maximum likelihood

Details

This function is primarily used to get a maximum likelihood fit of a linear mixed-effects model for an anova comparison.
