Contains functions in order to estimate diagnostic and prognostic capacities of continuous markers. More precisely, one function concerns the estimation of timedependent ROC (ROCt) curve, as proposed by Heagerty et al. (2000) <doi:10.1111/j.0006341X.2000.00337.x>. One function concerns the adaptation of the ROCt theory for studying the capacity of a marker to predict the excess of mortality of a specific population compared to the general population. This last part is based on additive relative survival models and the work of PoharPerme et al. (2012) <doi:10.1111/j.15410420.2011.01640.x>. We also propose two functions for cutoff estimation in medical decision making by maximizing timedependent expected utility function. Finally, we propose confounderadjusted estimators of ROC and ROCt curves by using the Inverse Probability Weighting (IPW) approach. For the confounderadjusted ROC curve (without censoring), we also proposed the implementation of the estimator based on placement values proposed by Pepe and Cai (2004) <doi:10.1111/j.0006341X.2004.00200.x>.
