*** The following discriminant function formulae were used in this cross testing:
Thai (King et al. 1998) F = 0.3229101* Maximum head diameter + 0.1298626* Epicondylar width 23.86411
Chinese (Iscan and Shihai 1995) F = 0.0876531* Midshaft circumference +
0.2399596* Maximum head
diameter 197.49596
South African white (Steyn and Iscan 1997) F = 0.1467735* Epicondylar width
+ 0.1817591* Maximum head
diameter 20.11745
American white (Iscan and Miller-Shaivitz 1984) F= 0.30829* Maximum head
diameter + 0.08253* Epicondylar
width 0.01607* Maximum length + 0.07202* Midshaft circumference 19.63418
