Predictability is a technique used in network analysis where each node is predicted by all the others. You then calculate the explained variance R2 for each node in the network. This is a Bayesian R2 because so far I have only seen it applied using the
BGGM package which uses Bayesian Gaussian Graphical Models.
One measure of node centrality is predictability, i.e. how much of the variance of a node that is explained by all other nodes in the network. Predictability in the BGGM framework is estimated using Bayesian R2 with 95% credible intervals from the posterior distribution.
