Learning dataset for logistic regression models

Description

This dataset includes 592 ossa coxae from five population samples. The eleven trichotomic traits are given for each os coaxe (possibly with missing values for incomplete bones), along with the geographical origin and known sex of the individual. When possible, the age and stature of the individual are also given. This dataset is used as a training sample for the logistic regression models implemented in PELVIS.
