The adult height of a girl can be predicted based on her height at the time of menarche.
The line equations are based on data from a nomogram in the Harriett Lane Handbook. For each age and menarche height the predicted height was recorded. This was then plotted in JMP and the following line equations were described.

predicted adult height in centimeters =
= (m * (height at menarche in centimeters)) + b
In the implementation, the age of menarche was rounded to the nearest 0.5.
