We are interested in network 𝐺, denoted by adjacency matrix 𝑨 and a set of edges 𝛿𝐺, denoted by 𝛿𝑨. It is assumed that the edges denoted by 𝛿𝑨 are missing, or spurious for that matter. When trying to establish the probability of one of these edges to be missing the quantity of interest is the posterior of 𝛿𝑨, 𝑃(𝛿𝑨|𝑨). This posterior can be written as follows :
