This booklet is worried with very important difficulties of strong (stable) statistical pat tern acceptance while hypothetical version assumptions approximately experimental facts are violated (disturbed). trend reputation concept is the sector of utilized arithmetic during which prin ciples and strategies are built for category and identity of gadgets, phenomena, approaches, occasions, and indications, i. e. , of items that may be laid out in a finite set of positive factors, or homes characterizing the items (Mathematical Encyclopedia (1984)). phases in improvement of the mathematical idea of development acceptance will be saw. on the first degree, until eventually the center of the Seventies, development recogni tion idea used to be replenished ordinarily from adjoining mathematical disciplines: mathe matical records, practical research, discrete arithmetic, and knowledge idea. This improvement degree is characterised by way of winning answer of trend acceptance difficulties of other actual nature, yet of the easiest shape within the experience of used mathematical versions. one of many major techniques to resolve development acceptance difficulties is the statisti cal method, which makes use of stochastic versions of function variables. less than the statistical strategy, the 1st degree of trend acceptance concept improvement is characterised by way of the idea that the likelihood information version is understood precisely or it's esti mated from a consultant pattern of enormous dimension with negligible estimation blunders (Das Gupta, 1973, 1977), (Rey, 1978), (Vasiljev, 1983)).
