pcor_mat function

Extract the Partial Correlation Matrix

Extract the partial correlation matrix (posterior mean) from estimate, explore, ggm_compare_estimate, and ggm_compare_explore objects. It is also possible to extract the partial correlation differences for ggm_compare_estimate and ggm_compare_explore objects.

pcor_mat(object, difference = FALSE, ...)

Arguments

• object: A model estimated with BGGM . All classes are supported, assuming there is matrix to be extracted.
• difference: Logical. Should the difference be returned (defaults to FALSE) ? Note that this assumes there is a difference (e.g., an object of class ggm_compare_estimate) and ignored otherwise.
• ...: Currently ignored.

Returns

The estimated partial correlation matrix.

Examples

# note: iter = 250 for demonstrative purposes

# data
Y <- ptsd[,1:5] + 1

# ordinal
fit <- estimate(Y, type = "ordinal",
                iter = 250,
                progress = FALSE)

pcor_mat(fit)
