%description
This is an implementation of the algorithm described in Section 3 of
Hosszejni and Frühwirth-Schnatter (2022) <doi:10.48550/arXiv.2211.00671>.
The algorithm is used to verify that the counting rule CR(r,1) holds for
the sparsity pattern of the transpose of a factor loading matrix. As
detailed in Section 2 of the same paper, if CR(r,1) holds, then the
idiosyncratic variances are generically identified. If CR(r,1) does not
hold, then we do not know whether the idiosyncratic variances are
identified or not.
