The 32 observations are European countries: BELGIUM, BULGARIA, CZECHREPUBLIC, DENMARK, GERMANY, ESTONIA, IRELAND, GREECE, SPAIN, FRANCE, ITALY, CYPRUS, LATVIA, LITHUANIA, LUXEMBOURG, HUNGARY, MALTA, NETHERLANDS, AUSTRIA, POLAND, PORTUGAL, ROMANIA, SLOVENIA, SLOVAKIA, FINLAND, SWEDEN, UNITEDKINGDOM, ICELAND, NORWAY, SWITZERLAND, CROATIA, TURKEY. The 3 variables are: the total unemployment rate, defined as the percentage of unemployed persons aged 15-74 in the economically active population (Variable 1); the youth unemployment rate, defined as the unemployment rate for young people aged between 15 and 24 (Variable 2); the long-term unemployment share, defined as the Percentage of unemployed persons who have been unemployed for 12 months or more (Variable 3). Non-spherical clusters seem to be present in the data. The Gustafson and Kessel-like fuzzy k-means should be used for finding them.
