To gain a better insight into recent vertical movements of the earth's crust obtained by geodetic measuring or for pinpointing more precisely the component of tectonic origin, different methodologies are applied.

Availability of the precise repeated levelling measuring data coupled with the preferred research methodology offer a chance to determine and predict recent vertical movements of the earth's crust.

By means of mathematical statistics analysis, the present study purposes to inquire into recent vertical movements of the earth's crust determined with the help of measuring; to predict vertical movements of the earth's crust in a selected territory and to estimate their intensity rate by using territorial geo-parameters (in this study, geo-parameters mean the geologic characteristics observed within a definite territory).

Vertical movements of the earth's crust are determined by geodetic methods, drawing on the findings provided by repeated measuring of geodetic levelling.

In order to study relations shared by vertical movements of the earth's crust and geo-parameters, all-round research is carried out, including the integrated analysis of territorial geo-parameters and data provided by geodetic measuring of recent movements of the earth's crust.

Initial estimation of relations shared by measured recent vertical movements of the earth's crust and territorial geo-parameters is performed by calculating the correlation coefficients for the values of measured vertical movements of the earth's crust and for the digital values of territory-defining geo-parameters (Rodionov 1981; Draper, Smith 1998; Spiegel, Stephens 2007):

F statistics are calculated for the estimation of the created regression model's adequacy for the measured velocities of vertical movements of the earth's crust along the route under examination.

If [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], then it is possible to argue, with a probability of p _ 1--q, that values obtained by using the regression model are adequate for the values of measured vertical movements of the earth's crust, i.

Possessing only a graphic image of the field of recent vertical movements of the earth's crust (a map of the velocities of vertical movements of the earth's crust) or the digital values of these movements at relevant points, the values of the horizontal gradients of movement velocities can be found by digital differentiation methods (Ulomov 2004).

For the inquiry into recent vertical movements of the earth's crust, a Lithuanian class I vertical network 4th levelling polygon (as shown in Fig.

For determining the relations shared by vertical movements of the earth's crust and territorial geo-parameters, the following territory-defining parameters are accepted:

Examination of the special qualities of relations shared by vertical movements of the earth's crust and geo-parameters in the territory under research contributed to the computation of correlation matrices along the following lines: Vilnius-Jonava, Jonava-Zarasai-Turmantas, Turmantas-Vilnius, and by bringing these lines into a single unit, i.
