THE COMPONENT STATISTICAL FACTOR ANALYSIS OF THE EXPECTED LIFE EXPECTANCY IN THE IMPLEMENTATION OF INFORMATION TECHNOLOGY
The demographic policy of the authorities in Russia is aimed primarily at increasing life ex-pectancy. This is reflected in population programs that are being developed, implemented and funded. A holistic information and methodological approach to the factor analysis of life expec-tancy is proposed on the basis of the formed system of statistical indicators that characterize the various socio-demographic situation in which each indicator finds its place. Within this ap-proach, the authors used the method of principal components to estimate the coefficients of the econometric model of life expectancy. This allowed reflecting the positive impact of the main factors identified: the standard of living of the population, demographic and economic security, the quality of health care. The practical significance of the study is confirmed by the results ob-tained and the possibility of their application to optimize management decisions of regional au-thorities to change the living conditions within the framework of adopted directions of socio-economic development.
Keywords: increase in life expectancy, healthy life expectancy, principal component method.
Highlights:
the necessity of understanding the variety of factors that determine the average life expec-tancy is considered;
the results of the performed component analysis are presented: three main components are identified, which reflect the impact of the formation of the factor indicators system on the ex-pected life expectancy;
the interpretation of the main components on the basis of the heuristic method application to their content (logical-theoretical) analysis is carried out.
