Description
An object of the intraclass module defines a zero mean multivariate Gaussian distribution by its covariance matrix \(\Sigma\) as
\[\begin{split}\Sigma_{ij} = \begin{cases}
\sigma^2, &\text{ if } i=j\\
\rho\sigma^2, &\text{ if } (i,j) \in E \\
\end{cases}\end{split}\]
and \(\Sigma^{−1}_{ij} = 0 \text{ if } (i, j) \in E \text{, where } \sigma^2 > 0 \text{ and } \rho \in [0, 1]\) denote the variance and correlation coefficient, respectively.
Using an object id of this module in the parameters_id
field of the data
section requires that graph_id
represents a decomposable graph.
