The World Health Organization (WHO) has published data on the physical development of infants and children up to 5 years of age.
Patient selection: length from 45 to 110 cm
Parameters:
(1) gender
(2) height in centimeters
(3) weight in kilograms
For each specified month in the tables, 3 variables are given:
(1) L = power in the Box-Cox transformation
(2) M = median
(3) S = generalized coefficient of variation
When L is not equal to 0:
Z-score for a value =
= ((((value) / M) ^ (L)) - 1) / (L * S)
