Abstract: | Various methods of interpolation (approximation, smoothing, and filtering types) which take measurement noise into account
(piecewise polynomial approximation, smoothing splines, kriging, filters, etc.) are analyzed. It is found that regularization
methods are used in all of them. The advantages and disadvantages of these methods are pointed out and prospects for the use
of program packages by nonspecialists in mathematics and information technology are examined. Recommendations regarding the
proper choice of estimation techniques, quality criteria, and parameters for monitoring them are made in the case where geofields
are to be approximated and modelled. |
