convert_to_parameter

zfit.param.convert_to_parameter(value, name=None, prefer_constant=True, params=None, lower=None, upper=None, step_size=None, *, label=None, dependents=None)

Convert a numerical to a constant/floating parameter or return if already a parameter. (deprecated arguments)

Deprecated: SOME ARGUMENTS ARE DEPRECATED: (dependents). They will be removed in a future version. Instructions for updating: Use params instead.

Parameters:

• value (Union[int, float, complex, Tensor, ZfitParameter, Callable]) – Value of the parameter. If a ZfitParameter is passed, it will be returned as is.

• name (str | None) – Name of the parameter. If None, a unique name will be created.

• prefer_constant (bool) – If True, create a ConstantParameter instead of a Parameter, if possible.

• params (ZfitParameter | Iterable[ZfitParameter] | None) – If the value is a callable, the parameters that are passed to the callable.

• lower (Union[int, float, complex, Tensor, ZfitParameter, None]) – Lower limit of the parameter.

• upper (Union[int, float, complex, Tensor, ZfitParameter, None]) – Upper limit of the parameter.

• step_size (Union[int, float, complex, Tensor, ZfitParameter, None]) – Step size of the parameter.

• label (str | None) – |@doc:param.init.label||@docend:param.init.label|

Return type:

ZfitParameter
