Algorithm 1

1: Initialize

β = η + (d - 1) / 2

2: For

k \in {1, 2, \dots, d - 1}

do:
3:

β \leftarrow β - 1 / 2

4: For

i \in {k + 1, k + 2, \dots, d}

do:
5: Generate

ρ_{k, i; 1, 2, \dots, k - 1} ~ B e t a (β, β)

6: End For
7: End For
8:

ρ_{i j; k L} = \frac{ρ_{i j; L} - ρ_{i k; L} ρ_{j k; L}}{(1 - ρ_{i k; L}^{2}) (1 - ρ_{j k; L}^{2})}
