pois.ord | R Documentation |
This function estimates the adjacency matrix of a Poisson model given a matrix of counts and topological ordering, using the Or-PPGM algorithm proposed in Nguyen et al. (2022).
pois.ord(X, maxcard, alpha, order)
X |
the matrix of counts (n times p). |
maxcard |
the uper bound of the cardinality of the conditional sets K. |
alpha |
the significant level of the tests. |
order |
the topological ordering of variables (names of nodes). |
the estimated adjacency matrix of the graph.
