bodyFat: Body Fat data

In tanujitdey/modelSampler: A unique tool for variable selection and model exploration in linear regression model

Description

Lists estimates of the percentage of body fat determined by underwater weighing and various body circumference measurements for 251 men. (see references below).

A variety of popular health books suggest that the readers assess their health, at least in part, by estimating their percentage of body fat. In Bailey (1994), for instance, the reader can estimate body fat from tables using their age and various skin-fold measurements obtained by using a caliper. Other texts give predictive equations for body fat using body circumference measurements (e.g. abdominal circumference) and/or skin-fold measurements. See, for instance, Behnke and Wilmore (1974), pp. 66-67; Wilmore (1976), p. 247; or Katch and McArdle (1977), pp. 120-132).

Format

bodyFat & Density determined from underwater weighing Percent body fat from Siri's (1956) equation. “bodyFat” is the outcome variable. The data frame containing:

age	Age (years)
weight	Weight (lbs)
height	Height (inches)
neck	Neck circumference (cm)
chest	Chest circumference (cm)
abdomen	Abdomen 2 circumference (cm)
hip	Hip circumference (cm)
thigh	Thigh circumference (cm)
knee	Knee circumference (cm)
ankle	Ankle circumference (cm)
biceps	Biceps (extended) circumference (cm)
forearm	Forearm circumference (cm)
wrist	Wrist circumference (cm)

(Measurement standards are apparently those listed in Benhke and Wilmore (1974), pp. 45-48 where, for instance, the abdomen 2 circumference is measured "laterally, at the level of the iliac crests, and anteriorly, at the umbilicus".)
