Description

leapgp is an R package designed for fast sequential emulation of computer models. Sequential emulation is common in applications requiring MCMC. The leapgp package is based on Rumsey et al. (2023) and can be viewed as a global model extension of the laGP method of Apley and Gramacy 2015.

To install the package, use

# install.packages("devtools")
devtools::install_github("knrumsey/leapgp")

The method is described in Rumsey et al. (2023) and explicit code examples are given in the vignette associated with this package.
