%description
Find the permutation symmetry group such that the covariance matrix of the
given data is approximately invariant under it. Discovering such a
permutation decreases the number of observations needed to fit a Gaussian
model, which is of great use when it is smaller than the number of
variables. Even if that is not the case, the covariance matrix found with
'gips' approximates the actual covariance with less statistical error. The
methods implemented in this package are described in Graczyk et al. (2022)
<doi:10.1214/22-AOS2174>.
