### Format

`diabetes` is a data frame with 11 variables (columns). The first column of the data frame contains the response variable (`diabetes$y`) which is a quantitative measure of disease progression one year after baseline. The rest of the columns contain the measurements of the ten explanatory variables (age, sex, body mass index, average blood pressure and six blood serum registers) obtained from each of the 442 diabetes patients.
