Statistical Modeling and Analysis of the Correlation between the Gross Domestic Product per Capita and the Life Expectancy

Abstract

This paper reflects the statistical modeling of the trends concerning the G.D.P. per capita and the Life Expectancy in 10 countries, in 2014, respectively the G.D.P. per capita and the Life Expectancy in Romania, between 2010-2014. With the help of the „Least Squares Method”, which is a method through we can to reflect the trend line of the best fit concerning a model. This research reflects that there is a strong intensity regarding the correlation between the G.D.P. per capita and the Life Expectancy in the world. So, if everyone’s needs of the people are satisfied, then any increase in G.D.P. per capita would barely affect life expectancy.
