Simulation design for Scenario 1
| Variables | X 1 | X 2 | X 3 | X 4 | X 5 | Y|X 2=0 | Y|X 2=1 |
|---|---|---|---|---|---|---|---|
| Distribution | N(0,1) | B(1,0.5) | DU(1/4) | DU(1/10) | DU(1/20) | B(1,0.5 - rel) | B(1,0.5 + rel) |
The variables are sampled independently from the following distributions. N(0,1) stands for the standard normal distribution. B(1, π) stands for the Binomial distribution with n = 1, i.e the Bernoulli distribution, and probability π. DU(1/n) stands for the Discrete Uniform distribution with values 1, …, n. The relevance parameter rel indicates the degree of dependence between Y and X 2, and is set at 0.1, which is not very high
