%description
A well known identifiability issue in factor analytic models is the
invariance with respect to orthogonal transformations. This problem
burdens the inference under a Bayesian setup, where Markov chain Monte
Carlo (MCMC) methods are used to generate samples from the posterior
distribution. The package applies a series of rotation, sign and
permutation transformations (Papastamoulis and Ntzoufras (2022)
<DOI:10.1007/s11222-022-10084-4>) into raw MCMC samples of factor
loadings, which are provided by the user. The post-processed output is
identifiable and can be used for MCMC inference on any parametric function
of factor loadings. Comparison of multiple MCMC chains is also possible.
