Representation of physical phenomena by hyper-random models / Gorban I.I. // Mathematical Machines and System. - 2007. - N 1. - P. 34 - 41.
Publications consented theory of hyper-random events, variables, processes, and fields have been analysed. It has been shown, that the theory belongs to ones, which describe constructive mathematical models. All results followed from it are equivalent to the results obtained from probability theory and mathematical statistics. However, as the box theory, it spreads the possibilities to solve practical tasks. Hyper-random models taking into consideration the changing of distribution functions of variables, processes, and fields more adequately describes the real situations than random ones with fixed distribution functions. It has been found the corollary of the hypothesis, that all real phenomena with the exception of the world physical constants are hyper-random type, is the absolutely all estimates of real, values, functions, and fields are not consistent type and the accuracy of any real physical measurements is limited. Apart this, the absolutely truth of target detection and absolutely truth of object classification are not possible. Refs.: 26 titles.
