Abstract

The paper analyzes practical aspects of using the index selection. The article describes mathematical and selection contradictions in the use of the selection index (SI) and methods of removing the same. The authors propose a resulting formula of determining the SI. The study presents the results of using the upgraded SI including the negative feature selection in comparison with the isolated selection. The aftereffect of the program embedded in the SI was demonstrated graphically and proved by the correlation and variance analysis.
