Survival Analysis Sample Data
The lecture-book format has a sequence of illustrations and formulae in the left column of each page and a script in the right column. The procedure is run and the output shows a summary of the entries as well as the sample size estimate. The Computer Appendix in the second edition of this text provided step-by-step instructions for using the computer packages stata, SAS, and spss to carry out the survival analyses presented in the main text. We also added a section that clarifies how to obtain confidence intervals for PH models that contain product terms that reflect effect modification of exposure variables of interest. An Introduction to Survival Analysis Using Stata, Second Edition, from within Stata using the net command.
An L1 and L2 penalised Cox models are available in penalized. The ICE package aims at estimating the hazard function for interval censored data.
Boosting: Gradient boosting for the Cox model is implemented in the gbm package. Sign test for matched pairs Median test for unmatched pairs Wilcoxon Signed-Ranks test for matched pairs - a non-parametric substitute for the paired Student t test when the data is not normally distributed. Power calculations for logistic regression with binary exposure- and covariables. Interactive Statistical Calculation Pages, sections of the t ( fo and statpages.

This web page will perform a proportional-hazards regression analysis and return the regression coefficients, their standard errors, hazard (risk) ratio, and their confidence intervals, and the baseline survivor curve, along with goodness-of-fit information.
Significance level corresponding to a correlation coefficient Testing the Correlation Coefficient - enter up to 42 r values, along with a postulated population r value.
Many built-in fit fuctions for structural equation modeling and other statistical modeling.
Exact Bayes test for independence in r by c contingency tables - Can also handle comparison of observed-vs-expected, and observed-vs-uniform situations.

Introduction to Survival Analysis
Sign and Binomial test - test an observed proportion against a proposed population proportion Mean, SD, confidence interval, etc. Cph in the rms package and the eha package propose some extensions to the coxph function. You can also use a faster version by Ronald Brand (Leiden University or an enhanced version by Kevin Sullivan (Emory University) that has illustrative examples and explanatory material. The NestedCohort fits Cox models for covariates with missing data. The coxrobust package proposes a robust implementation of the Cox model. The SvyNom package permits to construct, validate and calibrate nomograms stemming from complex right-censored survey data.
For example, rv computes a relative survival curve. Constructs simple experimental designs interactively and also constructs appropriate statistical software for the analysis of the designs. Calculate p-value from z, t, F, r, or Chi Square; or do the reverse.
