The present paper shows that the analysis of full flow X-ray activity signals recorded by the ASM (All-Sky Monitor) survey camera of RXTE (Rossi X-ray Timing Explorer) orbital observatory for binary systems allows for not only establishment of some mechanisms of matter accretion in binary star systems but classification depending on manifestation of statistical memory effects as well. As an example, using frequency dependencies of autocorrelators and their derivatives calculated on the basis of Memory Function For...

Development of information and computer technology is a factor in increased use of statistical methods in all sphere of action (geology, geophysics, ecology, astronomy and many others). Regression analysis (RA) is widely used in the prediction and assessment of model parameters. For many years the ordinary least squares estimation method (LSE, OLS), a computational scheme of RA, and its generalizations are widely used in practice. The disadvantage of the classical scheme of RA, is that with the compliance LSE assu...
