The data set can be used to test the grey-zone and 2-group models.
The data set is a data frame with 300 rows and 4 columns for patient survival time (time), censoring event (event), marker values (x), and true risk groups (xhigh=1 for high risk and 0 for low risk).
The data were generated based on a Weibull distribution for survival times and normal distributions for marker values in both the high and low risk patients.
The data were generated with the code in the Examples of
genSurvData in this package.
