Details

The model was fitted by the LMS model. Parameters are stored as type LMS. Tabulated values are point ages.

Height follows a normal distribution, with all lambda parameters set equal to 1. The standard deviation (in cm) is obtained as S*M.

The naming conventions are as follows:

list("nl4.hgt")

Length/Height (cm) for Age

list("nl4.wgt")

Weight (kg) for Age

list("nl4.wfh")

Weight (kg) for Height (cm)

list("nl4.bmi")

Head circumference (cm) for Age

list("nl4.lgl")

Leg Length (cm) for Age

list("nl4.hip")

Hip circumference (cm) for Age

list("nl4.wst")

Waist circumference (cm) for Age

list("nl4.whr")

Waist/Hip ratio for Age

list("nl4.sit")

Sitting Height for Age

list("nl4.shh")

Sitting Height/Height ratio for Age
