Description

In the presentation we consider systematic biases of fit parameters arising from a chi^2 minimization procedure, which we call "statistical biases of fit parameters". We discuss several possible techniques, which may reduce those statistical biases. That may be extremely useful, in paticular for precision experiments with high statistics, if for technical reasons, for systematic studies, etc., the whole data set has to be divided into many equal parts and then fit separately, and the weighted average being used as a final result. Some numerical estimates for the muon g-2 experiment are presented.
