partsurvfit function

Partitioned survival regression object

Create a partitioned survival regression object of class partsurvfit. The object contains a list of fitted survival models fit using either flexsurvreg or flexsurvspline (i.e., an object of class flexsurvreg_list) and the data frame used to perform the fit of each model. The same data frame must have been used for each fit.

partsurvfit(object, data)

Arguments

• object: An object of class flexsurvreg_list.
• data: The data frame used to fit each survival model in object. flexsurvreg.

Returns

Returns an object of class partsurvfit, which is a list containing two elements. The first element, "models", contains the survival models passed to object, and the second element, "data" contains the data frame passed to data.

Examples

library("flexsurv")
fit1 <- flexsurv::flexsurvreg(formula = Surv(endpoint1_time, endpoint1_status) ~ age, 
                              data = psm4_exdata$survival,
                              dist = "weibull")
fit2 <- flexsurv::flexsurvreg(formula = Surv(endpoint2_time, endpoint2_status) ~ age, 
                              data = psm4_exdata$survival, 
                              dist = "weibull")
fsreg_list <- flexsurvreg_list(endpoint1 = fit1, endpoint2 = fit2)
fits <- partsurvfit(fsreg_list, data = psm4_exdata$survival)
class(fits)
