bodyfat {isdals}

Body fat in women

Description

It is expensive and cumbersome to determine the body fat in humans as it involves immersion of the person in water. This dataset provides information on body fat, triceps skinfold thickness, thigh circumference, and mid-arm circumference for twenty healthy females aged 20 to 34. It is desirable if a model could provide reliable predictions of the amount of body fat, since the measurements needed for the predictor variables are easy to obtain.
