Objectives of the course 
Enhancement of the mathematical scope, acquaintance with new methods of mathematical reasoning, possession of methods of statistical analysis of economic problems
As a result of the course study a student have to be able: — to choose an adequate statistical model describing a certain economic object or phenomenon; — to perform analysis of an economic object or forecasting of an economic process within the framework of the chosen model by means of the “Statistica” computer package; — to construct the point and interval estimates for parameters; — to verify statistical hypotheses; — to construct tests for statistical check of hypotheses by methods of multivariate statistical analysis; — to perform analysis and make forecasts for time series.
