params.GP {plgp}

Extract parameters from GP particles

Description

Extract parameters from particles for Gaussian process (GP) regression, classification, or combined unknown constraint models

Usage

params.GP()
params.CGP()
params.ConstGP()

Details

Collects the parameters from each of the particles (contained in the global variable peach) into a data.frame that can be used for quick summary and visualization, e.g., via hist. These functions are also called to make progress visualizations in PL

Value

returns a data.frame containing summaries for each parameter in its columns
