### Description

`MEAN()` returns an iid model applied to the formula's response variable.

### Usage

    MEAN(formula, ...)

### Arguments

`formula` | Model specification.
`...` | Not used.

### Details

The model does not use any specials, and so everything on the formula's right-hand-side will be ignored.

### Value

A model specification.

### Specials

#### window

The `window` special is used to specify a rolling window for the mean.

    window(size = NULL)

`size` | The size (number of observations) for the rolling window. If NULL (default), a rolling window will not be used.
