Package: TwoTimeScales Title: Analysis of Event Data with Two Time Scales Type: Package Version: 1.2.1 Authors@R: c(person("Angela", "Carollo", email = "carollo@demogr.mpg.de", role = c("aut", "cre", "cph"), comment = c(ORCID = "0000-0002-5625-6553")), person("Paul H.C.", "Eilers", email = "p.eilers@erasmusmc.nl", role = "aut"), person("Jutta", "Gampe", email = "gampe@demogr.mpg.de", role = "aut")) URL: https://github.com/AngelaCar/TwoTimeScales, https://angelacar.github.io/TwoTimeScales/ Description: Analyse time to event data with two time scales by estimating a smooth hazard that varies over two time scales. If covariates are available, estimate a proportional hazards model with such a two-dimensional baseline hazard. Functions are provided to prepare the raw data for estimation, to fit the model and to plot the two-dimensional smooth hazard. Extension to a competing risks model are implemented.
