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.

pphsm
in
rms
translates an AFT model to a proportional
hazards form. The
polspline
package includes
the
hare
function that fits a hazard regression
model, using splines to model the baseline hazard. Hazards can be,
but not necessarily, proportional. The
flexsurv
package
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 allows
estimation of a Weibull Regression for a rightcensored endpoint,
one intervalcensored covariate, and an arbitrary number of
noncensored covariates.

Accelerated Failure Time (AFT) Models:

Wei and 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

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

can fit other types of models depending on the chosen
distribution,
e.g.
, a tobit model. The
AER
package provides the
tobit
function, which is a
wrapper of
survreg
to fit the tobit model. An
implementation of the tobit model for crosssectional data and
panel data can be found in the
censReg
package. The
timereg
package provides implementation of the
proportional odds model and of the proportional excess hazards
model. The

distribution to survival data. The model is based on describing
time to event as the barrier hitting time of a Wiener process,
where drift towards the barrier has been randomized with a
Gaussian distribution. The

package computes the
pseudoobservation for modelling the survival function based on
the KaplanMeier estimator and the restricted mean. The
fastpseudo
package dose the same for the restricted
mean survival time.

fits parametric
timetoevent models, in which any parametric distribution can be
used to model the survival probability, and where one of the
parameters is a linear function of covariates. The

Multistate Models

General Multistate Models:
The
coxph
function from package
survival
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

competing risks data based on the on the
inverseprobabilitycensoringweights and direct binomial
regression approach.

package permits to
fit the Fine and Gray model as well other models that belong to
the class of semiparametric generalized odds rate transformation
models to intervalcensored competing risks data.

Recurrent event data:
coxph
from the
survival
package can be used to analyse recurrent event
data. The
cph
function of the
rms
package
fits the AndersonGill model for recurrent events, model that can

reReg
package. The
spef

from censored survival data using nonparametric weight
adjustments.

Simulation

The

conditional on an userspecified list of (possibly timedependent)
covariates.

The
prodlim

simulating complex event history data.

The

multistate models. The package allows for a general specification
of the transition hazard functions, for nonMarkov models and
for dependencies on the history.

complex multistate models data with possibly nonlinear baseline
hazards and nonlinear covariate effects.

complex survival data such as recurrent event data and competing
risks.

The
simsurv
package enables the user to simulate
survival times from standard parametric survival distributions
(exponential, Weibull, Gompertz), 2component mixture distributions,
or a userdefined hazard or log hazard function. Time dependent
effects (i.e. nonproportional hazards) can be included by
interacting covariates with linear time or some transformation of
time.

The
MicSim
package provides routines for performing
continuoustime microsimulation for population projection. The
basis for the microsimulation are a multistate model, Markov or
nonMarkov, for which the transition intensities are specified, as
well as an initial cohort.

The
SimHaz
package permits to simulate data with a
dichotomous timedependent exposure.

The
SimSCRPiecewise
package can be used to simulate
univariate and semicompeting risks data given covariates and
piecewise exponential baseline hazards.

The
SimSurvNMarker
package provides functions to
simulate from joint survival and potentially multivariate marker
models. Userdefined basis expansions in time can be passed
which effect the log hazard, the markers, and the association
between the two.

This section tries to list some specialised plot functions that might be
useful in the context of event history analysis.

The

the x axis.

to draw the states and transitions that characterize a multistate
model.

The

package provides many plot functions for
representing multistate data, in particular Lexis diagrams.
