x.test: A data set used in example of 'recur.bart'.

In timebart: timebart: Survival Analysis with BART

Description

A matrix containing the testing set for a real data example of recurrent events survival analysis. There are 488 patients in the cohort: 235 in the training set and 253 in the testing set. See the Reference below (and the References therein) for more detailed information; a brief synopsis follows.

x.test contains both the training set and the testing set. There are 798 unique time points so there are 235*798=187530 rows of the training set followed by 253*798=201894 rows of the testing set. For patient's who died prior to the end of follow-up, their external factors are last value carried forward. Therefore, we can use x.test to estimate the cumulative hazard for all patients for all time points.
