select.ggm_compare_explore function

Graph selection for ggm_compare_explore Objects

Provides the selected graph (of differences) based on the Bayes factor \insertCite williams2020comparingBGGM.

## S3 method for class 'ggm_compare_explore'
select(object, BF_cut = 3, ...)

Arguments

• object: An object of class ggm_compare_explore.
• BF_cut: Numeric. Threshold for including an edge (defaults to 3).
• ...: Currently ignored.

Returns

The returned object of class select.ggm_compare_explore contains a lot of information that is used for printing and plotting the results. For users of BGGM , the following are the useful objects:

• adj_10 Adjacency matrix for which there was evidence for a difference.
• adj_10 Adjacency matrix for which there was evidence for a null relation
• pcor_mat_10 Selected partial correlation matrix (weighted adjacency; only for two groups).
