##### Refit a Model by Maximum Likelihood Criterion

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

##### Usage
refitML(x, …)
# S3 method for 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.

##### Details

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

##### Value

an object like x but fit by maximum likelihood

refit and update.merMod for more extensive refitting.
