Least square fitting with one explicit parameter less

Description

Abstract It is shown that whenever the multiplicative normalization of a fitting function is not known, least square fitting by ^(χ2)minimization can be performed with one parameter less than usual by converting the normalization parameter into a function of the remaining parameters and the data. Title of program: FITM1 Catalogue Id: AEYG_v1_0 Nature of problem Least square minimization when one of the free parameters is the multiplicative normalization of the fitting function.
