MarkovAutoregression.smooth(params, transformed=True, cov_type=None, cov_kwds=None, return_raw=False, results_class=None, results_wrapper_class=None)

Apply the Kim smoother and Hamilton filter

Parameters:

  • params (array_like) – Array of parameters at which to perform filtering.

  • transformed (bool, optional) – Whether or not params is already transformed. Default is True.

  • cov_type (str, optional) – See fit for a description of covariance matrix types for results object.

  • cov_kwds (dict or None, optional) – See fit for a description of required keywords for alternative covariance estimators

  • return_raw (bool,optional) – Whether or not to return only the raw Hamilton filter output or a full results object. Default is to return a full results object.

  • results_class (type, optional) – A results class to instantiate rather than MarkovSwitchingResults. Usually only used internally by subclasses.

  • results_wrapper_class (type, optional) – A results wrapper class to instantiate rather than MarkovSwitchingResults. Usually only used internally by subclasses.

Return type:

MarkovSwitchingResults
