Survival analysis, also called event history analysis in social science,
or reliability analysis in engineering, deals with time until occurrence
of an event of interest. However, this failure time may not be observed
within the relevant time period, producing socalled censored observations.
This task view aims at presenting the useful R packages for the analysis
of time to event data.

implements the model of Royston and Parmar (2002). The model uses
natural cubic splines for the baseline survival function, and
proportional hazards, proportional odds or probit functions for
regression. The
SurvRegCensCov
package fits a Weibull
regression model for rightcensored data in which one covariate
might be censored.

Ying (1994) goodnessoffit for Cox regression models) and the
partly parametric additive risk model of McKeague and Sasieni. A
version of the CoxAalen model for interval censored data is
available in the
coxinterval
package.

BuckleyJames Models:
The
bj
function in
rms
and
BJnoint

package fits the BuckleyJames
model with highdimensional covariates (L2 boosting, regression
trees and boosted MARS, elastic net).

pseudoobservation for modelling the survival function based on
the KaplanMeier estimator and the restricted mean.

Multistate Models

General Multistate Models:
The
coxph

can be fitted for any
transition of a multistate model. It can also be used for
comparing two transition hazards, using correspondence between
multistate models and timedependent covariates. Besides, all the
regression methods presented above can be used for multistate
models as long as they allow for lefttruncation.
The
mvna
package provides convenient functions for
estimating and plotting the cumulative transition hazards in any
multistate model, possibly subject to rightcensoring and
lefttruncation. The

continuoustime Markov and hidden Markov multistate models to
longitudinal data. Transition rates and output processes can be
modelled in terms of covariates. The

time. The distribution of the waiting times can be chosen between
the exponential, the Weibull and exponentiated Weibull
distributions. Nonparametric estimates in illnessdeath models
and other three state models can be obtained with package
p3state.msm. The

model observed under rightcensored survival times and interval
or rightcensored progression times. The

semiparametric with Msplines approximation of the baseline
intensities.
