This package implements a variety of such\nmethods, including zero-variance control variates (ZV-CV, Mira\net al. (2013) ), regularised\nZV-CV (South et al., 2023 ), control\nfunctionals (CF, Oates et al. (2017) )\nand semi-exact control functionals (SECF, South et al., 2022\n). ZV-CV is a parametric approach\nthat is exact for (low order) polynomial integrands with\nGaussian targets. CF is a non-parametric alternative that\noffers better than the standard Monte Carlo convergence rates.\nSECF has both a parametric and a non-parametric component and\nit offers the advantages of both for an additional\ncomputational cost. Functions for applying ZV-CV and CF to two\nestimators for the normalising constant of the posterior\ndistribution in Bayesian statistics are also supplied in this\npackage. The basic requirements for using the package are a set\nof samples, derivatives and function evaluations.", "BugReports": "https://github.com/LeahPrice/ZVCV/issues", "License": "GPL (>= 2)", "LazyLoad": "yes", "LazyData": "true", "Encoding": "UTF-8", "RoxygenNote": "7.3.1", "NeedsCompilation": "yes", "Packaged": { "Date": "2026-10-16 09:53:52 UTC", "User": "root" }, "Author": "Leah F.
