final

Time Series of a Seasonal Adjustment Model

Functions to extract the main time series from a "seas" object. For universal import of X-13ARIMA-SEATS tables, use the series function.

Usage

final(object)
original(object)
trend(object)
irregular(object)
# S3 method for seas
residuals(object, ...)

Details

These functions support R default NA handling. If na.action = na.exclude is specified in the call to seas, the time series will also contain NAs.

final(m)
original(m)
irregular(m)

# NA handling
AirPassengersNA <- window(AirPassengers, end = 1962, extend = TRUE)
final(seas(AirPassengersNA, na.action = na.omit))    # no NA in final series
final(seas(AirPassengersNA, na.action = na.exclude)) # NA in final series
final(seas(AirPassengersNA, na.action = na.x13))     # NA filled by x13
# final(seas(AirPassengersNA, na.action = na.fail))    # fails
