Back-transforms a bivariate siber ellipse fitted to z-scored data to the original location and scale. Not intended for direct call by users.
ellipseBackTransform(jags.output, siber, idx.community, idx.group)
A 6 x n matrix representing the back-transformed posterior
distributions of the bivariate normal distribution for a specified group
within a specified community, where n is the number of
posterior draws in the saved sample. The first four columns are the
covariance matrix Sigma in vector format. This vector converts to the
covariance matrix as matrix(v[1:4], nrow = 2, ncol = 2)
. The
remaining two columns are the back-transformed means.
a mcmc.list object of posterior samples created by
rjags::rjags()
. In siber this is created typically by fitEllipse()
a siber object as created by createSiberObject.
an integer specifying which community to back-transform.
an integer specifying which group to back-transform.
