Technologies of Numerical Investigation and Applying of Data-Based Modeling Methods. S. Yefimenko, V. Stepashko

Abstract. In the paper a general methodology of investigations of modelling methods from data observed with the use of statistical tests is suggested based on statement of a problem of choosing the most effective modelling algorithm. The software tools that realize the general methodology of investigations are developed. The software tools were used for investigation and applying of modelling methods. The practical problems of the automated models building were solved with the use of developed software tools.

Keywords. Computer tests, modeling from data, recurrent parameter estimation.
