(params, transformed=True, includes_fixed=False, complex_step=False, **kwargs)¶ Loglikelihood evaluation
- Parameters
params : array_like
Array of parameters at which to evaluate the loglikelihood function.
transformed : bool, optional
Whether or not params is already transformed. Default is True.
**kwargs
Additional keyword arguments to pass to the Kalman filter. See KalmanFilter.filter for more details.

update
modifies the internal state of the Model to reflect new params
Notes
[R154] recommend maximizing the average likelihood to avoid scale issues; this is done automatically by the base Model fit method.
