\title{Evaluating Smoothing Spline Hazard Estimates}
\description{
Evaluate smoothing spline hazard estimates by \code{sshzd}.
}
\usage{
hzdrate.sshzd(object, x, se=FALSE)
hzdcurve.sshzd(object, time, covariates=NULL, se=FALSE)
survexp.sshzd(object, time, covariates=NULL, start=0)
}
\arguments{
\item{object}{Object of class \code{"sshzd"}.}
\item{x}{Data frame or vector of points on which hazard is to be
evaluated.}
\item{se}{Flag indicating if standard errors are required.}
\item{time}{Vector of time points.}
\item{covariates}{Vector of covariate values.}
\item{start}{Optional starting times of the intervals.}
}
\value{
For \code{se=FALSE}, \code{hzdrate.sshzd} returns a vector of hazard
evaluations. For \code{se=TRUE}, \code{hzdrate.sshzd} returns a
list consisting of the following components.
\item{fit}{Vector of hazard evaluations.}
\item{se.fit}{Vector of standard errors for log hazard.}
For \code{se=FALSE}, \code{hzdcurve.sshzd} returns a vector or
columns of hazard curve(s) evaluated on \code{time} points at the
\code{covariates} values. For \code{se=TRUE}, \code{hzdrate.sshzd}
returns a list consisting of the following components.
\item{fit}{Vector or columns of hazard curve(s).}
\item{se.fit}{Vector or columns of standard errors for log hazard
curve(s).}
\code{survexp.sshzd} returns a vector of expected survivals, which
are based on the cumulative hazards over the specified intervals.
