Description

An object of this module defines a Bayesian network by generating the weight matrix \(W\) of a Gaussian linear structural equation model (SEM) of the form

\[Y_i=\sum_{j:Y_j\in pa(Y)} W_{ij}Y_j + Z_i,\]

where \(Z_i\sim \mathcal N(\mu, \sigma^2)\) and elements of \(W\) are distributed as

\[\begin{split}W_{ij} \sim \begin{cases} \mathrm{Unif}([a, b])\mathrm{Unif}(\{-1,1\}) & \text{ if }(i, j) \in E\\ 0 & \text{ otherwise.} \end{cases}\end{split}\]
