QDiabetes Sample Dataset

Description

A simulated sample dataset for exploring the use of the QDR2013, QDR2018A, QDR2018B and QDR2018C type 2 diabetes risk prediction functions of this package.

Details

A simulated dataset containing the characteristics of 50 subjects (one per row). No relationships have been simulated between variables. The dataset contains no values or combinations of values that would result in warnings or errors from any of the risk prediction functions in this package. It exists purely to allow for testing and exploration of these functions.
