BDgraph (version 2.7)

phat: Posterior edge inclusion probabilities

Description

According to the output of BD-MCMC algorithm, this function gives us the posterior edge inclusion probabilities for all possible edges.

Usage

phat(output, round = 3)

Arguments

output

a list which is the result of BD-MCMC algorithm from the 'bdgraph' function.

round

a number for rounding all probabilities to the specified number of decimal places (default 3).

Value

• phat
  upper triangular matrix which shows the posterior inclusion probabilities for all possible edges.
