Simulates the Huessler--Reiss extremal functions on a tree
simu_px_tree_HR(n, Gamma_vec, A)
Numeric matrix \(n\times d\). Simulated data.
Number of simulations.
Numeric vector with \(d - 1\) elements, where \(d\) is the number of nodes in the tree (and \(d - 1\) is the number of edges).
Numeric matrix \(d \times (d - 1)\); the rows represent the nodes in the tree, the columns represent the edges. For a fixed node \(k = 1, \dots, d\), each entry \((i, j)\) is equal to 1 if the edge in position \(j\) is on the directed path from node \(k\) to node \(i\) in the polytree rooted at node \(k\).
