gen_height_weight {httk} | R Documentation |
Generate heights and weights for a virtual population.
Description
Predict height and weight from age using smoothing splines, and then add residual variability from a 2-D KDE, both fitted to NHANES data, for a given combination of gender and NHANES race/ethnicity category.
Usage
gen_height_weight(gender, reth, age_months, nhanes_mec_svy)
Arguments
gender |
Gender for which to calculate height/weight ("Male" or "Female") |
reth |
NHANES race/ethnicity category for which to calculate height/weight ("Mexican American", "Non-Hispanic Black", "Non-Hispanic White", "Other", or "Other Hispanic") |
age_months |
vector of ages in months for individuals for whom to calculate height/weight (between 0-959 months) |
nhanes_mec_svy |
|
Details
This function should usually not be called directly by the user. It is used by
httkpop_generate()
in "virtual-individuals" mode, after drawing gender,
NHANES race/ethnicity category, and age from their NHANES
proportions/distributions.
Value
A list containing two named elements, weight
and height
,
each of which is a numeric vector. weight
gives individual body
weights in kg, and height
gives individual heights in cm,
corresponding to each item in the input age_months
.
