Bayes Linear Emulation of Simulated Crop Yield

Hasan, Muhammad Mahmudul and Cumming, Jonathan A. (2021) 'Bayes Linear Emulation of Simulated Crop Yield.', in Applied Statistics and Data Science:Proceedings of Statistics 2021 Canada, Selected Contributions. Cham: Springer, pp. 145-151. Springer Proceedings in Mathematics & Statistics., 375


The analysis of the output from a large-scale computer simulation experiment can pose a challenging problem in terms of size and computation. We consider output in the form of simulated crop yields from the Environmental Policy Integrated Climate (EPIC) model, which requires a large number of inputs—such as fertilizer levels, weather conditions, and crop rotations—inducing a high dimensional input space. In this paper, we adopt a Bayes linear approach to efficiently emulate crop yield as a function of the simulator fertilizer inputs. We explore emulator diagnostics and present the results from emulation of a subset of the simulated EPIC data output.
