bank: bank dataset (Chapter 4)

Description Usage Format Source Examples

Description

The bank dataset we analyze in the first part of Chapter 3 comes from Flury and Riedwyl (1988) and is made of four measurements on 100 genuine Swiss banknotes and 100 counterfeit ones. The response variable y is thus the status of the banknote, where 0 stands for genuine and 1 stands for counterfeit, while the explanatory factors are bill measurements.
