##### Methods for Fitted ARMA Models

Methods for fitted ARMA model objects.

##### Usage

```
## S3 method for class 'arma':
coef(object, \dots)
## S3 method for class 'arma':
vcov(object, \dots)
## S3 method for class 'arma':
residuals(object, \dots)
## S3 method for class 'arma':
fitted(object, \dots)
## S3 method for class 'arma':
print(x, digits = max(3, getOption("digits") - 3), ...)
## S3 method for class 'arma':
plot(x, ask = interactive(), ...)
```

##### Arguments

- object, x
- an object of class
`"arma"`

; usually, a result of a call to`arma`

. - digits
- see
`printCoefmat`

. - ask
- Should the
`plot`

method work interactively? See`interactive`

. - ...
- further arguments passed to or from other methods.

##### Value

- For
`coef`

, a numeric vector; for`vcov`

, a numeric matrix; for`residuals`

and`fitted`

a univariate time series; for`plot`

and`print`

, the fitted ARMA model object.
