plot,fgpm-method

This method provides a diagnostic plot for the
 validation of regression models. It displays a calibration plot
 based on the leave-one-out predictions of the output at the
 points used to train the model.

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>.
