1	data(lung)

A balanced data set with respect to the times at which observations recorded. The data consists of the following variables on each patient:

ID: patient identifier.
FVC: forced vital capacity (%) determined at 3-month intervals from the baseline.
time_RE: time at visit at 3-month intervals.
intercept: column of 1's for model setup.
time: time at visit at 3-month intervals. Same as time_RE.
FVC0: forced vital capacity (%) at baseline.
FIB0: baseline lung fibrosis.
CYC: treatment allocation. Coded as 1 = oral cyclophosphamide; 0 = placebo.
FVC0.CYC: interaction term between FVC0 and CYC.
FIB0.CYC: interaction term between FIB0 and CYC.
time.CYC: interaction term between time and CYC.
time.CYC: interaction term between time and CYC.
surv: time to treatment failure or death.
failure_type: treatment failure/death indicator. Coded as 0 = censored; 1 = death; 2 = treatment failure.
