The aim of this study is to determine the geocenter dynamics described by dynamic adaptive regression and the general laws of DORIS and GPS navigation systems. A spatial geocenter dynamics can be represented as coordinate and time series. Mathematical description of the time series allows for determination of systematic change in the geocenter dynamics. To improve the accuracy of modeling and forecasting of the geocenter dynamics and to identify the regular effects, the dynamic regression modeling approach is used...

The aim of this paper is to analyze magnetohydrodynamic (MHD) solar activity on the basis of modeling and predicting the Wolf number dynamics. This study is based on the use of adaptive regression modeling approach implemented in the software package ARDM (adaptive regression dynamic modeling). The preliminary data was investigated for the presence of trend stability with fractal analysis.Currently, not only the experts in the field of solar physics, climatologists, and researchers in many fields related to the is...

Since the global information networks are well developing and the amount of information is rapidly increasing, an automatization of the analytical data processing has become more urgent. In their combination a solid basis for the improvement of management and operation packages in any field of activity arises. It should be noted the initial assumptions of the regression analysis are always observed. However, discovering that the preconditions are violated is not sufficient. A specific software package containing p...
