Model Specification Extractor

Description

Extracts a model specification (class “tsissm.spec”) from an object of class “tsissm.estimate”.

Usage

## S3 method for class 'tsissm.estimate'
tsspec(
  object,
  y = NULL,
  lambda = NULL,
  xreg = NULL,
  parameters = "initial",
  ...
)

Arguments

object	an object of class “tsissm.estimate”.
y	an optional new xts vector.
lambda	an optional lambda parameter for the Box Cox transformation (if previously used).
xreg	an optional matrix of regressors.
parameters	whether to set the parameters to their initial values, “initial” or the optimally estimated “optimal”.
...	not currently used.

This function is used by other functions in the package such as the backtest which requires rebuilding the specification for each re-estimation step with updated data but keeping all else equal.
