posteriorSEA {SIBER}

Calculate the SEA based on a posterior distribution of Sigma

Description

This function loops over each posterior draw of a single group's Bayesian bivariate ellipse and calculates the Standard Ellipse Area (SEA) for each draw, thereby generating a distribution of SEA estimates. Not intended for direct calling outside of siberEllipses().

Usage

posteriorSEA(post)

Arguments

post

a matrix of posterior covariance matrices and mean estimates for a bivariate ellipse. In SIBER, this is typically one list element of the object returned by siberMVN().

Value

A vector of posterior Bayesian Standard Ellipse Areas (SEA_B)
