Quasi-linear methods for the information model building for the Earth tidal irregular rotation

Modern stochastic information technologies for scientific research (using a priori and a posteriori data) are based on the stochastic correlationalmodel building methods. Off-line and on-line quasi-linear methods based on equivalent statistical linearization of nonlinear stochastic differential equations of the Earth tidal irregular rotation (on half year intervals) are considered. Ten testing examples for MATLAB software from informational resources on RAS fundamental problem “Statistical Dynamics of the EarthMotion” are presented.
