Despite encouraging results, quantitative characterization and comparison of GPSM-generated probability distributions is still lacking. It is currently unclear whether GPSMs can faithfully reproduce the complex multi-residue mutation patterns observed in natural sequences arising due to epistasis. We develop a set of sequence statistics to assess the \"generative capacity\" of three GPSMs of recent intere","authors_text":"Allan Haldane, Francisco McGee, Quentin Novinger, Ronald M.
