An integrate multivariate analytical approach is presented herein forsimplifying the work needed to determine the preferred scope of pompany stan-dardization. By integration and extraction a few new variables are obtained,representative of the primitive or old factors that are too many and too comp-lex. The application of the matrix principle, of similitude to the working-out of the matrix characteristic roots and vectors and to the introduction ofthe transition factor Cij into the linear combi nation of the old variables,enables the new variables to contain most of the information the old one...
