Methods for Fitted ARMA Models

Description

Methods for fitted ARMA model objects.

Usage

## S3 method for class 'arma'
coef(object, ...)
## S3 method for class 'arma'
vcov(object, ...)
## S3 method for class 'arma'
residuals(object, ...)
## S3 method for class 'arma'
fitted(object, ...)
## 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.
