Prussian Horse Kick Data

The number of soldiers in the Prussian cavalry killed by horse kicks from 1875 to 1894

Originator: Ladislaus Bortkiewicz

The data give the number of soldiers in the Prussian cavalry killed by horse kicks, by corp membership and by year. The years are from 1875 to 1894, and there are 14 different cavalry corps: the first column corresponds to the guard corp and the other columns to corps 1 through 11, 14, and 15. The data are from Distributome project and are derived from the 1985 book: Data: A Collection of Problems from Many Fields for the Student and Research Worker by David F. Andrews and A. M. Herzberg. The original source of the data is the classic 1898 book by von Bortkiewicz: Das Gesetz der kleinen Zahlen [The law of small numbers]. The data are famous because they seem to fit the Poisson model reasonably well.
