Survival Analysis

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 so-called censored observations.

This task view aims at presenting the useful R packages for the analysis of time to event data.

  • ipdmeta provides tools for individual patient data meta-analysis, mixed-level meta-analysis with patient level data and multivariate survival estimates for aggregate studies.
  • The KMsurv package includes the data sets from Klein and Moeschberger (1997). Some supplementary data sets and functions can be found in the OIsurv package. The package SMIR that accompanies Aitkin et al. (2009), SMPracticals that accompanies Davidson (2003) and DAAG that accompanies Maindonald, J.H. and Braun, W.J. (2003, 2007) also contain survival data sets.
  • The SvyNom package permits to construct, validate and calibrate nomograms stemming from complex right-censored survey data.
  • The logconcens package compute the MLE of a density (log-concave) possibly for interval censored data.
  • The TBSSurvival package fits parametric Transform-both-sides models used in reliability analysis
  • The OutlierDC package implements algorithms to detect outliers based on quantile regression for censored data.
  • The coarseDataTools package implements an EM algorithm to estimate the relative case fatality ratio between two groups.
  • The GSSE package proposes a fully efficient sieve maximum likelihood method to estimate genotype-specific distribution of time-to-event outcomes under a nonparametric model
  • power and sample size calculation based on the difference in restricted mean survival times can be performed using the SSRMST package.
  • The AHR package allows for the estimation of multivariate average hazard ratios as defined by Kalbfleisch and Prentice.
  • The survMisc provides miscellaneous routines to help in the analysis of right-censored survival data.
  • Accompanying data sets to the book Applied Survival Analysis Using R can be found in package asaur.
