BDgraph (version 2.70)

precision: Estimated precision matrix

Description

Provides the estimated precision matrix.

Usage

precision( bdgraph.obj, round = 2 )

Value

matrix which corresponds the estimated precision matrix.

Arguments

bdgraph.obj

object of S3 class "bdgraph", from function bdgraph. It also can be an object of S3 class "ssgraph", from the function ssgraph::ssgraph() of R package ssgraph::ssgraph().

round

value for rounding all probabilities to the specified number of decimal places.
