Kolesnik A.N., Mustafina D.R. DEFINITION OF BASIC PARAMETERS ON HEAVY METALS IN ECOLOGICALLY DANGEROUS ZONESTo determine the basic parameters in multiparameter researches a matrix of research has been constructed. We find the matrix of factor loadings using the principal of components method. Varimax rotation in the space of factors was carried out, the maximum loading by absolute factor was found, and the association of the parameters of factors was identified. Polynomial models were constructed for all parameters of the study. Determination of contribution of the parameters-arguments was realized by constructing models for each option. A comparative analysis of quality of group conditioning with quantitative parameters of conditionality was conducted in this paper.Key words: load factor, polynomial model, the matrix of the study, the basic parameter.
