Generalized autoregressive conditional heteroscedasticity in-mean model allows accounting for both time-varying variance and risk premium in financial time series data. This paper introduces an extension of this particular model with more flexible parameterization of the way variance enters the...

The article raises the question of possible existence of gaps, ruptures in the probability scale and of possible values of these ruptures. The calculations give 1/3 of the standard deviation as the minimal value of these ruptures for a number of standard distributions.

The monograph is devoted to use of distributed and parallel calculations in MATLAB interface. The technology is approved on standard problems of linear algebra. The industrial approach for identification of mathematical models of difficult systems on the basis of MATLAB parallel technics is...

In a paper construction branch forecasting model which allows to estimate the industry development problems is shown. Difference from anthers models, in given paper the main attention is turned to the building of the living area. Model stands from sub model (blocks): amount of apartments, real...

A normative balance mathematical model for regional economy contains a lot of unspecified parameters which are not defined directly by the data of economic statistics. Only confidence intervals for the unknown parameters can be computed from the statistical data. A method for estimation of the...

Accidents forecast of various nature with sufficient economic damage, maximal loss enhancement, elimination of their consequences is a national wide problem It is an important concern of authorities and all levels management In order to solve this problem we need a forecast system for...

The paper demonstrates the potential of the stochastic frontier-based methods of performance assessment of non-profit associations. They are commonly used for productivity analysis and could serve as an adequate tool for such assessment, especially when dealing with numerous non-profits pursuing...
