Kalman smoothing

Parameters

paramsarray_like

Array of parameters at which to evaluate the loglikelihood function.

transformedboolean, optional

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

return_ssmboolean,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

**kwargs

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