FIELD: statistical data manipulation methods.
SUBSTANCE: initial approximation of useful signal evaluation is received with iterative refining. Further useful signal approximations in every sliding interval position are formed in consequent approximation unit as a result of iterative application of least squares method to received evaluations. Method is realized in procedure of variation-weighted quadratic approximations with vector weight function of least modules method until the difference between consequent approximations, which come to evaluation storage register, is less than defined threshold level.
EFFECT: reduced influence of measurement dispersion.
