UnobservedComponents.score_obs(params, method='approx', transformed=True, includes_fixed=False, approx_complex_step=None, approx_centered=False, **kwargs)¶

Compute the score per observation, evaluated at params

Parameters:¶

paramsarray_like

Array of parameters at which to evaluate the score.

**kwargs

Additional arguments to the loglike method.

Returns:¶

scorendarray

Score per observation, evaluated at params.

Notes

This is a numerical approximation, calculated using first-order complex step differentiation on the loglikeobs method.
