prostate.dat

This is an artificial prostate cancer dataset used for illustrating the usage of functions in <code>QHScrnomo</code>

datasets

Nomograms are constructed to predict the cumulative incidence
rate which is calculated after adjusting for competing causes to the event of interest.
K-fold cross-validation is implemented to validate predictive accuracy using a competing-risk version of the concordance index.
Methods are as described in: Kattan MW, Heller G,
Brennan MF (2003).
