A total of 122 adult human pubes (66 males and 56 females) are used in this study of a discriminant function analysis for determining sex from four pubic measurements: the angle formed by the middle line of the superior ramus and inferior ramus of pubis (in degrees, X1), subpubic angle (in degrees, X2), the minimum distance from the symphyseal surface to the obturator (in millimeters, X3), and the minimum thickness of the ischiopubic ramus (in millimeters, X4). The method introduced by Fisher is used. Using the formula Y = 0.270X1 −0.985 X2 − 0.761X3 + 1.806X4, F = 200 (F > F0.01(4,117), P < 0.01), section point −32.47, an accuracy of 100% could be achieved for 230 pubes (130 males, 100 females).
