%description
For emulating multifidelity computer models. The major methods include
univariate autoregressive cokriging and multivariate autoregressive
cokriging. The autoregressive cokriging methods are implemented for both
hierarchically nested design and non-nested design. For hierarchically
nested design, the model parameters are estimated via standard
optimization algorithms; For non-nested design, the model parameters are
estimated via Monte Carlo expectation-maximization (MCEM) algorithms. In
both cases, the priors are chosen such that the posterior distributions
are proper. Notice that the uniform priors on range parameters in the
correlation function lead to improper posteriors. This should be avoided
when Bayesian analysis is adopted. The development of objective priors for
autoregressive cokriging models can be found in Pulong Ma (2020)
<DOI:10.1137/19M1289893>. The development of the multivariate
autoregressive cokriging models with possibly non-nested design can be
found in Pulong Ma, Georgios Karagiannis, Bledar A Konomi, Taylor G Asher,
Gabriel R Toro, and Andrew T Cox (2019) <arXiv:1909.01836>.
