Special cases also\nimplemented include Bayesian linear models, CART, treed linear\nmodels, stationary separable and isotropic GPs, and GP\nsingle-index models. Provides 1-d and 2-d plotting functions\n(with projection and slice capabilities) and tree drawing,\ndesigned for visualization of tgp-class output. Sensitivity\nanalysis and multi-resolution models are supported. Sequential\nexperimental design and adaptive sampling functions are also\nprovided, including ALM, ALC, and expected improvement. The\nlatter supports derivative-free optimization of noisy black-box\nfunctions. For details and tutorials, see Gramacy (2007)\n and Gramacy & Taddy (2010)\n.", "Maintainer": "Robert B.
