Bayesian framework

Its framework is nonparametric and Bayesian, based on Gaussian process priors.Read 12 Oct 2026 · nsaph-software.github.io

Covariate adjustment

The documented workflow converts covariate values into a composite generalized propensity score before fitting Gaussian processes.Read 12 Oct 2026 · nsaph-software.github.io

Covariate processing

The standard Gaussian process workflow converts covariate values into a composite score called the generalized propensity score before fitting Gaussian processes.Read 12 Oct 2026 · nsaph-software.github.io

Curve estimation

The standard Gaussian process workflow estimates an exposure-response function and visualizes a pointwise 95% credible band.Read 12 Oct 2026 · nsaph-software.github.io

Installation
