Overview"
Garn developed a list of multipliers for converting a child's current height to the predicted adult height.
Parameters:
(1) gender of the patient
(2) age of the patient
(3) current height in centimeters
predicted adult height in cm =
= (current height in cm) * (multiplier for age and gender)

A common rule of thumb is that a child's adult height is twice the height recorded on the second birthday.
If this data is analyzed in Minitab
For a female from to 0 to 4 years:
multiplier = (0.0375 * ((age)^2)) - (0.4165 * (age)) + 2.682
For a female from to 4 to 15 years:
multiplier = (0.003656 * ((age)^2)) - (0.1257 * (age)) + 2.056
For a male from to 0 to 4 years:
multiplier = (0.0675 * ((age)^2)) - (0.5765 * (age)) + 2.962
For a male from to 4 to 16 years:
multiplier = (0.002168 * ((age)^2)) - (0.1009 * (age)) + 2.079
