RecursiveLS.filter(return_ssm=False, **kwargs)[source]#

Kalman filtering

Parameters:
paramsarray_like

Array of parameters at which to evaluate the loglikelihood function.

transformedbool, optional

Whether or not params is already transformed. Default is True.

includes_fixedbool, optional

If parameters were previously fixed with the fix_params method, this argument describes whether or not params also includes the fixed parameters, in addition to the free parameters. Default is False.

complex_stepbool, optional

Whether or not to compute the filtered output using complex step differentiation. Default is False.

return_ssmbool,optional

Whether or not to return only the state space output or a full results object. Default is to return a full results object.

cov_typestr, optional

See MLEResults.fit for a description of covariance matrix types for results object.

cov_kwdsdict or None, optional

See MLEResults.get_robustcov_results for a description required keywords for alternative covariance estimators

results_classtype, optional

A results class to use for results object. Default is MLEResults.

results_wrapper_classtype, optional

A results wrapper class to use for the results object. Default is MLEResultsWrapper.

low_memorybool, optional

If set to True, techniques are applied to substantially reduce memory usage. If used, some features of the results object will not be available (including in-sample prediction), although out-of-sample forecasting is possible. Default is False.

**kwargs

Additional keyword arguments to pass to the Kalman filter. See KalmanFilter.filter for more details.
