2SPcurves
2SPcurves R Package (under development at GitHub)
Software to accompany research on using an ROC inspired approach to create two-sample survival probability curves that complement traditional analysis of survival data. See repo for further details.
BivRec
Bivariate Alternating Recurrent Event Data Analysis (BivRec) R Package
Alternating recurrent event data arise frequently in biomedical and social sciences where two types of events such as hospital admissions and discharges occur alternatively over time. In this package, we implemented one nonparametric and two semiparametric methods to analyze this type of data.
-
The function bivrecReg is used for estimation of covariate effects on the two alternating event gap times (xij and yij) based on semiparametric methods. The method options are "Lee.et.al" and "Chang".
-
The bivrecNP function is used for the estimation of the joint cumulative distribution function (cdf) for the two alternating events gap times (xij and yij) as well as the marginal survival function for the Type I gap times (xij) and the conditional cdf of the Type II gap times (yij) given an interval of the Type I gap times (xij) in a nonparametric fashion.

The package also provides options to simulate and visualize the data and the results of the analysis
