The computer program is assumed to be a Gaussian process,\nwhose parameters are estimated using Bayesian techniques that\ngive a PDF of expected program output. This PDF is conditional\non a training set of runs, each consisting of a point in\nparameter space and the model output at that point. The\nemphasis is on complex codes that take weeks or months to run,\nand that have a large number of undetermined input parameters;\nmany climate prediction models fall into this class. The\nemulator essentially determines Bayesian posterior estimates of\nthe PDF of the output of a model, conditioned on results from\nprevious runs and a user-specified prior linear model. The\npackage includes functionality to evaluate quadratic forms\nefficiently.", "License": "GPL", "URL": "https://github.com/RobinHankin/emulator", "BugReports": "https://github.com/RobinHankin/emulator/issues", "Repository": "https://robinhankin.r-universe.dev", "Date/Publication": "2025-04-19 06:59:45 UTC", "RemoteUrl": "https://github.com/robinhankin/emulator", "RemoteRef": "HEAD", "RemoteSha": "f35327ba516e9ebcb8fb9dd0fe0e3a93a05a7957", "NeedsCompilation": "no", "Packaged": { "Date": "2026-05-19 06:28:19 UTC", "User": "root" }, "Author": "Robin K.
