Graph Selection for ggm_compare_estimate Objects

Provides the selected graph (of differences) based on credible intervals for the partial correlations that did not contain zero Williams2019BGGM.

Usage

# S3 method for class 'ggm_compare_estimate'
select(object, cred = 0.95, ...)

Arguments

object

An object of class estimate.default.

cred

Numeric. The credible interval width for selecting the graph (defaults to 0.95; must be between 0 and 1).

...

Value

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

• mean_diff A list of matrices for each group comparsion (partial correlation differences).

• pcor_adj A list of weighted adjacency matrices for each group comparsion.

• adj A list of adjacency matrices for each group comparsion.
