An implementation of the cross-validated difference in means (CVDM) test by Desmarais and Harden (2014) doi:10.1007/s11135-013-9884-7 (see also Harden and Desmarais, 2011 doi:10.1177/1532440011408929) and the cross-validated median fit (CVMF) test by Desmarais and Harden (2012) doi:10.1093/pan/mpr042. These tests use leave-one-out cross-validated log-likelihoods to assist in selecting among model estimations. You can also utilize data from Golder (2010) doi:10.1177/0010414009341714 and Joshi & Mason (2008) doi:10.1177/0022343308096155 that are included to facilitate examples from real-world analysis.
