Table 1.
Six models considered in simulations, where p is the number of the variables, q is the number of covariates and n is the sample size. pr(Θij ≠ 0) and pr(Γij ≠ 0) specify the sparsity of the model.
Model | (p, q, n) | pr(Θij ≠ 0) | pr(Γij ≠ 0) |
---|---|---|---|
1 | (100, 100, 250) | 2/p | 3/q |
2 | (50, 50, 250) | 2/p | 4/q |
3 | (25, 10, 250) | 2/p | 3.5/q |
4 | (1000, 200, 250) | 1.5/p | 20/q |
5 | (800, 200, 250) | 1.5/p | 25/q |
6 | (400, 200, 250) | 2.5/p | 20/q |
