The R Journal, 10:2, pp. 317-3252073-4859http://hdl.handle.net/10347/18402This paper describes the implementation of a flexible method in R for fitting a regression model to possibly non-Markov progressive illness-death data. The idmTPreg package offers the user the opportunity to estimate possibly time-varying effect of covariates on the transition probabilities for the progressive illness-death model. We have explained the use of the idmTPreg package by applying the method to a colon cancer dataset. The results in this paper were obtained using R 3.4.2. In a future version of the package, we plan to implement a similar method to estimate coefficients on net survivals for a progressive illness-death in a relative survival settingengThis article and supplementary materials are licensed under a Creative Commons Attribution 4.0 International licenseAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/journal articleopen access
