The invention relates to computing and can be used in the study of random processes, for example, in determining the value of a forbidden parameter by a number of indirect parameters that have a linear relationship with forbidden and change the values of their probability functions in time.

The purpose of the invention is to expand the functionality of the device.

In the process of using complex technical systems, their state (healthy — not healthy) is determined by monitoring a certain amount of control parameters. At the same time, there are a number of parameters that are highly informative but prohibited to be measured, since such a measurement is connected with the termination of the use of the system for its intended purpose. In this case, the values of the forbidden parameter can be determined by the values of the number of allowed indirect parameters, have a linear correlation to the relationship, a relationship with a forbidden parameter. During operation due to wear, aging, etc. parameters of random characteristics of forbidden and indirect parameters are changed.

The task of determining the value of the forbidden control parameter, taking into account changes in the parameters of random characteristics, is reduced to solving a regression equation of the form
