Data set with three explanatory variables and response variable body fat for 20 healthy females aged 35-44

1 |

A data frame with four columns:

- Triceps
triceps skinfold thickness

- Thigh
thigh circumference

- Midarm
midarm circumference

- BodyFat
body fat

The data set contains three explanatory variables and the response variable body fat for 20 healthy females aged 35-44. As the variable body fat is very expensive to obtain, predicting it with the cheaper dimensional measurements is desirable. There is substantial multicollinearity among the explanatory variables.
