%description
Fit model for datasets with easy-to-interpret Gaussian process modeling,
predict responses for new inputs. The input variables of the datasets can
be quantitative, qualitative/categorical or mixed. The output variable of
the datasets is a scalar (quantitative). The optimization of the
likelihood function can be chosen by the users (see the documentation of
EzGP_fit()). The modeling method is published in "EzGP: Easy-to-Interpret
Gaussian Process Models for Computer Experiments with Both Quantitative
and Qualitative Factors" by Qian Xiao, Abhyuday Mandal, C. Devon Lin, and
Xinwei Deng (2022) <doi:10.1137/19M1288462>.
