Parameters:

paramsarray_like: Array of new parameters.
transformedbool, optional: Whether or not params is already transformed. If set to False, transform_params is called. 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 derivatives via a complex-step approximation. Default is False.
