splines2 is a complementary package on splines providing functions constructing B-spline, monotone spline (M-spline) and its integral (I-spline), convex spline (C-spline), and integral of B-spline basis. Piecewise constant basis is allowed for B-spline and M-spline basis.
reda mainly provides function fitting gamma frailty model with baseline rate function modeled by regression splines for recurrent event data, as well as functions computing and ploting the mean cumulative funciton from sample (Nelson-Aalen estimator) and the fitted frailty model. Most functions are S4 methods that produce S4 class objects.
dynsurv provides functions to fit time-varying coefficient models for interval censored and right censored survival data. Three major approaches are implemented:
touch provides tools of unilization and cost in healthcare is an R implementation of the software tools developed in the H-CUP (Healthcare Cost and Utilization Project) at AHRQ (Agency for Healthcare Research and Quality). It currently contains functions to map ICD9 code to AHRQ comorbidity measures.
