ptFCReg                 Functional concurrent regression using
                        pointwise multiple linear regression.
smPtFCRegCoef           Smooth the concurrent effects functions in a
                        'ptFCReg' object using local linear regression.
                        The local linear regression is implemented
                        using the function 'Lwls1D'.
