INVESTIGATION OF LIFE SATISFACTION IN OECD COUNTRIES WITH MULTIVARIATE ANALYSIS METHODS

Abstract

The quality of life index is an index used to measure the quality of life for countries. When this index value is calculated, countries are assessed in terms of the multivariate features they have. The significance of the variables studied in the index studies is not generally investigated statistically. In this study, it is aimed to create a classification mechanism with the help of other subindex values which are thought to affect life satisfaction and constitute quality of life. With the help of this classification mechanism, it was also determined whether the statistical effects of variables affecting life satisfaction are significant. There are many techniques for performing the classification process. However, the literature does not focus on the reliability of these techniques. As with all statistical techniques, the validity and reliability of the results obtained from these techniques depend on the provision of the necessary assumptions. For this reason, various classification techniques have been introduced and evaluated in this study. It has been mentioned which one should be preferred according to the situations that can be encountered in practice.
