data_valid: Example Validation Data for 'rmodcal' Package
In syeeun/rmodcal: Assessing Risk Model Calibration with Missing Covariates

Example cohort with simulated case-cohort study where N = 10000 and 250 cases. This dataset is used to run the example for function model.calibration.

1	data_valid

A data frame with N = 10000 rows and 8 variables:

X: continuous covariate available in phase 1
Z: continuous covariate only available in phase 2; NA if missing
Uz: an ancillary predictor for Z2 available in phase 1
eventime: time-to-event (event = either case or censored)
ind.fail: binary outcome status (1 = case; 0 = non-case)
ind.ph2: phase 2 inclusion status (1 = included as a case or selected control; 0 = otherwise)
incl.prob: inclusion probability
wgt: sampling weights (=1/incl.prob)
