## Refit a Model by Maximum Likelihood Criterion

### Description

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

### Usage

    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.

### 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
