In drisso/learn2count: Structure Learning for Count Data

Structure learning with Poisson models using the Or-PPGM algorithm

Description

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).

Usage

pois.ord(X, maxcard, alpha, order)

Arguments

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).

Value

the estimated adjacency matrix of the graph.
