## Probabilities of observing the event in control arm during follow-up
p0_e1 <- 0.59 # Death
p0_e2 <- 0.74 # Disease Progression
## Effect size (Cause specific hazard ratios) for each endpoint
HR_e1 <- 0.91 # Death
HR_e2 <- 0.77 # Disease Progression
## Hazard rates over time
beta_e1 <- 2 # Death --> Increasing risk over time
beta_e2 <- 1 # Disease Progression --> Constant risk over time
## Correlation
rho <- 0.1 # Correlation between components
rho_type <- 'Spearman' # Type of correlation measure
copula <- 'Frank' # Copula used to get the joint distribution
## Additional parameter
case <- 3 # 1: No deaths; 2: Death is the secondary event;
# 3: Death is the primary event; 4: Both events are death by different causes
