predict.seas

Seasonal Adjusted Series

Description

Returns the seasonally adjusted series of an (optionally re-evaluated) model of class "seas". Without further arguments, this is equivalent to a call to the final() function.

Usage

## S3 method for class 'seas'
predict(object, newdata, ...)

Arguments

`object`	an object of class `"seas"`.
`newdata`	an object of class `"ts"`. new data values for the `x` argument in the `seas()` function.
`...`	further arguments, passed to `update.seas()`, to re-evaluate the model.

Details

With the newdata argument supplied, the "seas" object is re- evaluated, using the original model call. This is equivalent of calling final(update(m, x = newdata)).

Value

Object of class "ts".

Examples

# Using data from Dec. 59 to estimate a model
ap.short <- window(AirPassengers, end = c(1959, 12))
m <- seas(ap.short)
predict(m)
final(m)     # equivalent

# Use Dec. 59 model specification to estimate data up to Dec. 60
predict(m, AirPassengers)
