pyBASS

A python implementation of Bayesian adaptive spline surfaces (BASS). Similar to Bayesian multivariate adaptive regression splines (Bayesian MARS) introduced in Denison et al. (1998).

Installation

# pip
pip install pybass-emu

# uv
uv add pybass-emu

Examples

• Example 1 - univariate response
• Example 2 - multivariate/functional response
