Factor analysis of body hair distributions.
Using observations on the presence or absence of terminal hair in 13 locations on 700 white adult males, descriptive statistics were tabulated, phi coefficients of intercorrelation were computed, principal axis factor loadings were extracted, and varimax rotation of factors to simple structure was performed. The resulting rotated factors were interpreted as five independent components of body hair distribution: dorsal (less sacral), pubic extension, thoracic, sacral, and abdominal.
