Backtransforms a bivariate siber ellipse fitted to zscored data to the original location and scale. Not intended for direct call by users.
1  ellipseBackTransform(jags.output, siber, idx.community, idx.group)

jags.output 
a mcmc.list object of posterior samples created by

siber 
a siber object as created by createSiberObject. 
idx.community 
an integer specifying which community to backtransform. 
idx.group 
an integer specifyging which group to backtransform. 
A 6 x n matrix representing the backtransformed 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 backtransformed means.
