Source: R/posterior.R
VarCorr.brmcoda.Rd

Calculates the estimated standard deviations, correlations and covariances of the group-level terms of the brmsfit object in a brmcoda object.

Usage

# S3 method for class 'brmcoda'
VarCorr(x, ...)

Arguments

x

An object of class brmcoda.

...

Further arguments passed to VarCorr.brmsfit.

Value

A list of lists (one per grouping factor), each with three elements: a matrix containing the standard deviations, an array containing the correlation matrix, and an array containing the covariance matrix with variances on the diagonal.
