%description
Nonparametric methods for landmark prediction of long-term survival
outcomes, incorporating covariate and short-term event information. The
package supports the construction of flexible varying-coefficient models
that use discrete covariates, as well as multiple continuous covariates.
The goal is to improve prediction accuracy when censored short-term events
are available as predictors, using robust nonparametric procedures that do
not require correct model specification and avoid restrictive parametric
assumptions found in alternative methods. More information on these
methods can be found in Parast et al. 2012
<doi:10.1080/01621459.2012.721281>, Parast et al. 2011
<doi:10.1002/bimj.201000150>, and Parast and Cai 2013
<doi:10.1002/sim.5776>. A tutorial for this package is available here:
