bone_mass_age

Predict bone mass

Description

Predict bone mass from age_years, height, weight, gender, using logistic equations fit to data from Baxter-Jones et al. 2011, or for infants < 1 year, using equation from Koo et al. 2000 (See Price et al. 2003)

Usage

bone_mass_age(age_years, age_months, height, weight, gender)

Arguments

`age_years`	Vector of ages in years.
`age_months`	Vector of ages in months.
`height`	Vector of heights in cm.
`weight`	Vector of body weights in kg.
`gender`	Vector of genders, either 'Male' or 'Female'.

Value

Vector of bone masses.
