%description
Construction and smart selection of Gaussian process models for analysis
of computer experiments with emphasis on treatment of functional inputs
that are regularly sampled. This package offers: (i) flexible modeling of
functional-input regression problems through the fairly general Gaussian
process model; (ii) built-in dimension reduction for functional inputs;
(iii) heuristic optimization of the structural parameters of the model
(e.g., active inputs, kernel function, type of distance). An in-depth
tutorial in the use of funGp is provided in Betancourt et al. (2024)
<doi:10.18637/jss.v109.i05> and Metamodeling background is provided in
Betancourt et al. (2020) <doi:10.1016/j.ress.2020.106870>. The algorithm
for structural parameter optimization is described in
<https://hal.science/hal-02532713>.
