diabetes: Blood and other measurements in diabetics.

In nclSLR: The nclSLR package.

Description

Data collected in a study concerning patients with diabetes. The response variable of interest was disease progression one year after taking baseline measurements on various clinical variables. For each of n=442 patients, the data comprise a quantitative measure of disease progression (dis) and measurements on p=10 baseline (explanatory) variables: age (age), sex (sex), body mass index (bmi), average blood pressure (map) and six blood serum measurements (tc, ldl, hdl, tch, ltg, glu). The explanatory variables have been transformed to have mean 0, with sum of squares equal to 1.
