class slophep.Fitting.PDFBase.PDFBase(name: str, predobj: ObservableBase)[source]

Bases: object

property binning: ndarray: PDF binning scheme, optional

getVal(parname: str)[source]: Get a PDF parameter value

link_param(name_int: str, name_manager: str)[source]: Link a PDF shape parameter to parameter in the manager

link_params(link_dict: dict = {})[source]: Link multiple parameters, using dictionary of form {internal_name : manager_name}

normpdf() → ndarray[source]

Normalised PDF. Returns pdf() normalised to sum to 1.

Returns:: Normalised PDF histogram
Return type:: np.ndarray

property param_manager: ParameterManager: Manager for PDF parameters

property params_link: dict: Correspondence between names of shape parameters used internally in PDF and names of parameters themselves

property params_list: list[str]: List of PDF parameters

pdf() → ndarray[source]

Produce predicted histogram using values in parameter manager

Returns:: PDF histogram
Return type:: np.ndarray
Raises:: NotImplementedError – PDF implemented by user in a derived class

property predobj: ObservableBase: Observable object used for PDF

setVal(parname: str, val: float)[source]: Set a PDF parameter value

setVals(pars: dict)[source]: Set several PDF parameter value, using dictinoary of form {internal_name : value}

set_binning(binning: ndarray)[source]: Set PDF binning, optional

set_param_manager(param_manager: ParameterManager)[source]: Set parameter manager of PDF
