RCTRecruit: Non-Parametric Recruitment Prediction for Randomized Clinical Trials

Description

Accurate prediction of subject recruitment for Randomized Clinical Trials (RCT) remains an ongoing challenge. Many previous prediction models rely on parametric assumptions. We present functions for non-parametric RCT recruitment prediction under several scenarios.
