Details

The data was taken from the book [1] and is in fact a small subset of a pan-European demographic survey. It includes information about 32 persons, 16 represent northern Europe (Scandinavians) and 16 are from the Mediterranean regions. In both groups there are 8 male and 8 female persons. The data includes both quantitative and qualitative variables and is particularly useful for benchmarking exploratory data analysis methods.
