%description
Provides Gaussian process (GP) regression tools for social science
inference problems.  GPs combine flexible nonparametric regression with
principled uncertainty quantification: rather than committing to a single
model fit, the posterior reflects lesser knowledge at the edge of or
beyond the observed data, where other approaches become highly
model-dependent.  The package reduces user-chosen hyperparameters from
three to zero and supplies convenience functions for regression
discontinuity (gp_rdd()), interrupted time-series (gp_its()), and general
GP fitting (gpss(), gp_train(), gp_predict()).  Methods are described in
Cho, Kim, and Hazlett (2026) <doi:10.1017/pan.2026.10032>.
