TI  - A Robust Alternative to Environmental Performance Index
AB  - A composite index called the Environmental Performance Index (EPI) was obtained to
evaluate countries’ environmental performance. This index was calculated for 180 countries
concerning 24 environmental indicators. However, it is well known that there are huge differences
between countries regarding environmental factors besides social, economic, and cultural factors. This
case aggravates the doubt that the data set has outliers. Therefore, the index values should be obtained
such that they are unsensitive to outliers. This study aims to generate a composite index, which is a
robust alternative to EPI. For this aim, we use the Robust Principal Component Analysis (ROBPCA)
and the Technique for Order Preferences by Similarity to an Ideal Solution (TOPSIS), which is a multicriteria
decision-making method.
