Abstract

The aim of this paper is to provide a methodological guide on how to select, test, and use statistical procedures for sex estimation using morphological traits of the cranium expressed on an ordinal scale. R functions were developed to implement binary logistic regression (BLR) and linear discriminant analysis (LDA), and step-by-step instructions with examples from Cretan and Cypriot modern identified skeletal samples were provided to illustrate the potential and limitations of each method. Even though the current case study focused on cranial traits, the R functions provided may be used for any morphological skeletal trait.
