%description
Performs emulation of dynamic simulators using Gaussian process via
one-step ahead approach. The package implements a flexible framework for
approximating time-dependent outputs from computationally expensive
dynamic systems. It is specifically designed for nonlinear dynamic systems
where full simulations may be costly. The underlying Gaussian process
model accounts for temporal dependency through the one-step-ahead
formulation, allowing for accurate emulation of complex dynamics.
Hyperparameters are estimated via maximum likelihood. See Heo (2025,
<doi:10.48550/arXiv.2503.20250>) for exact method, and Mohammadi,
Challenor, and Goodfellow (2019, <doi:10.1016/j.csda.2019.05.006>) for
methodological details.
