Vectors of logical values to determine subjects who belong to
 <code>UP</code> and <code>DOWN</code>, respectively.

upp, dwn

Scalar value indicating a time to determine evnet/non-event.

Internaly used function by <code>nricens</code> to provide the NRI estimator
 by the Kaplan-Meier(KM) method.
 In the comparison for time to event models, it is possible to use
 directly when <code>UP</code> and <code>DOWN</code> subjects are known.

Calculating the net reclassification improvement (NRI) for risk prediction models with time to event and binary data.
