Absolute Risk Difference

Calculates the Absolute Risk Difference (ARD) from a Risk Ratio and baseline risk using simulations. The result is ARD as a decimal. The number of replications is fixed at 100,000.

Baseline risk
Baseline risk lower limit confidence interval
Baseline risk upper limit confidence interval
Risk ratio
Risk ratio lower limit confidence interval
Risk ratio upper limit confidence interval
Seed that is used for the simulation to ensure reproducibility
