After the classification, we can deal with the two kinds of indexes differently. Npm”+10 Positive index: Fiut Ruus-Ru Ru 100 R t in where i is the one of five metrics, L is the subindex of the metric i j is the one of the Rumin is the minimum value of the subindex of the metric i in the statistical data, and Rulmax is the maximum value of the subindex of the metric i in the statistical data, and Fai is the value of the i subindex of the metric i after standardization Determine the weights. We can get the value of every metric using the function F where n is the number of the subindex in metric i and a is a weight of the tetric i Get the final score of the evaluated country. Based on the discussion above we get the function S k where k is the number of metrics (in our case k= 5) Comparisons between Methods Before the comparison, each component measure was rescaled on a o to 100 scale for healthy life expectancy H Health-20 80-20×100 for health inequality, HI=(1-HealthInequality)x 100数学中国 www.madio.net
