   Sammanfattning : "Principal Components Regression" (PCREG), also sometimes called "biased regression methods" is used to model data with highly correlated explanatory variables. This well-known method has been discussed by multiple previous authors (Marquardt 1970, Hoerl and Kennard 1970, Lott 1973, Hawkins 1973, Webster, Grace and Mason 1974, Hoerl, Kennard and Baldwin 1975, Marquardt and Snee 1975, Hocking, Speed and Lynn 1976 Smith and Campbell 1980, Park 1981).

   Sammanfattning : Many studies show that socioeconomic and demographic variables have a strong link with human health which in turn affects life expectancy and age. This paper presents the results of a principal component regression analysis, in order to describe a good regression model for mean age of the population of all the countries in the world. LÄS MER
