Simulate data from a single two-arm trial with an exponentially distributed time-to-event endpoint and no predictor of the intercurrent event
Usage
sim_dat_one_trial_exp_nocovar(
n,
nt,
prob_ice,
fu_max,
prop_cens = 0,
T0T_rate,
T0N_rate,
T1T_rate,
T1N_rate
)
Arguments
- n
Positive integer value, number of subjects in the trial.
- nt
Positive integer value, number of treated subjects.
- prob_ice
Numeric value on the interval \((0,1)\), probability of the intercurrent event of interest (i.e. the event that determines the principal stratum membership).
- fu_max
Positive integer value, maximum follow-up time in days (administrative censoring assumed afterwards).
- prop_cens
Numeric value on the interval \([0,1)\), proportion of uniformly censored patients (default is 0).
- T0T_rate
Positive numeric value, monthly event rate in control subjects that would develop the intercurrent event if treated.
- T0N_rate
Positive numeric value, monthly event rate in control subjects that never develop the intercurrent event.
- T1T_rate
Positive numeric value, monthly event rate in treated subjects that develop the intercurrent event.
- T1N_rate
Positive numeric value, monthly event rate in treated subjects that never develop the intercurrent event.
