  "Description": "Provides a computationally efficient method (at least at\nthe time of development!) for robust additive modeling based on\nthe gamma divergence, implementing the methodology of Hui,\nDing, and Sugasawa (2026) <doi:10.1007/s11222-026-10960-3>. The\nmethod assumes an identity link and normally distributed\nerrors, and applies the gamma divergence to the resulting\nrestricted maximum likelihood function so as to obtain a loss\nfunction that is less sensitive to outlying responses. Because\n'gdam' uses a model fitted via the 'mgcv' package as the\nstarting point for optimization, and leverages many of its\nexisting techniques for estimation and inference, users can\ntake advantage of many of the smoothing options available in\nthe 'mgcv' package for constructing additive models.",
