%description
Implements multi-armed bandit approaches for pricing experiments with an
unknown demand curve, as developed in Weaver, Kumar, and Jain (2025)
"Nonparametric Pricing Bandits Leveraging Informational Externalities to
Learn the Demand Curve" <doi:10.1287/mksc.2022.0247>. Includes Upper
Confidence Bound (UCB) and Thompson Sampling (TS) baselines, Gaussian
process variants (GP-UCB, GP-TS), monotonic Gaussian process variants that
constrain demand to be weakly decreasing in price, and heterogeneous-noise
extensions. The willingness-to-pay distribution is fully user-specified
via a vector of consumer valuations, so any demand environment can be
simulated or replayed.
