Two-sampled Paired Test Data

Description

This data set consists the measurements of low-density lipoprotein (LDL), oxidized low-density lipoprotein (OxLDL) and the corresponding diagnosis. OxLDL is thought to be the active molecule in the process of atherosclerosis, so its proponents believe that its serum concentration should provide more accurate risk stratification than the traditional LDL assay.

Usage
