Diabetes data

These data consist of observations on 442 patients, with the response of interest being a quantitative measure of disease progression one year after baseline.
There are ten baseline variables---age, sex, body-mass index, average blood pressure, and six blood serum measurements---plus quadratic terms, giving a total of 64 features.

First used in LARS paper

Note that these data are first standardized to have zero mean and unit L2 norm before they are used in the examples.

Here are the standardized data (text file), and the 442 x 64 matrix (text file) for the "quadratic model"
