Continuous mark-specific relative risks for two groups CRAN Task View: Survival (http://CRAN.R-project.org/view=Survival) Estimation and testing of continuous mark-specific relative risks in two groups as described in Gilbert, P., McKeague, I. and Sun, Y. (2008) The 2-sample problem for failure rates depending on a continuous mark: an application to vaccine efficacy. Biostatistics 9, 2, 263-276. This package implements the methods presented in the paper for testing mark-specific hazards ratios and for estimation of mark-specific incidence ratios that are cumulative in time or cumulative in both time and the continuous mark.
