The L, M and S values for each measurement correspond respectively to the
Box-Cox power, median and coefficient of variation of the distribution by
age and sex (Cole & Green 1992). The short names and units for each measurement (see
LMS2z) are as follows: height (ht, cm), weight (wt, kg) and body mass
index (bmi, kg/m2).
