The package supports the construction of flexible\nvarying-coefficient models that use discrete covariates, as\nwell as multiple continuous covariates. The goal is to improve\nprediction accuracy when censored short-term events are\navailable as predictors, using robust nonparametric procedures\nthat do not require correct model specification and avoid\nrestrictive parametric assumptions found in alternative\nmethods. More information on these methods can be found in\nParast et al. 2012 , Parast\net al. 2011 , and Parast and Cai\n2013 .
