### ABSTRACT

Calculation methods have been proposed for the Hurst factor for univariate and multivariate TS on the basis of the main diagonals of TS tensor models. It is shown that the problem complexity determines the joint use of several mathematical theories, in particular, the tensor and multivariate matrix analysis. The examples of using the proposed methods are presented.
