Data Set Information:
We generated two batches of data, where each batch consists of 20 datasets.
For the low dimensional batch, we used 5 predictive parameters, of which 2 were dummy parameters (i.e. had no impact) and three were predictive.
For the medium dimension batch, we used 25 predictors, of which 2 were dummy and 23 predictive.
In each batch, we varied the event rate from 10% to 70% and the censor rate from 0% to 70% in 20% steps, and used a set population size of 3000.
This therefore led to two batches, each of 20 datasets of 3000 subjects.
Attribute Information:

x.2 & Uniform: [1,2,3,4]
x.3 & Binary: 0.6 chance of 0
x.4 & Uniform: [1,2,3]
For the medium dimension batch:
