The method suggests to use a sophisticated scheme for the appproximation of the drift of the tidal records. The drift is represented separately in subintervals of the record through polynomials of a variable power. An optimum power is estimated for every subinterval by testing statistical hypotheses through the criteria of Fisher and Akaike (AJC) and multiple analysis of all data for every value of the polynomial's power.spajournal articleopen access528Geodesia2504 Geodesia
