Use Fixed-Interval Smoothing on Time Series

Share:

Description

Performs fixed-interval smoothing on a univariate time series via a state-space model. Fixed-interval smoothing gives the best estimate of the state at each time point based on the whole observed series.

Usage

1
tsSmooth(object, ...)

Arguments

object

a time-series fit. Currently only class "StructTS" is supported

...

possible arguments for future methods.

Value

A time series, with as many dimensions as the state space and results at each time point of the original series. (For seasonal models, only the current seasonal component is returned.)
