Covers\nthe independent and dependent 't' test, between-subjects,\nwithin-subjects, and split-plot factorial analysis of variance,\nand multiple regression. The method is described in Anderson,\nKelley, and Maxwell (2017) . The\nnoncentrality parameter underlying the correction is obtained\nby direct numerical root finding, a more accurate approach than\na fixed grid search that also removes an internal upper limit\non the parameter. A small number of planned sample sizes\ntherefore differ slightly from versions 1.x; the new values are\nmore accurate.", "License": "GPL (>= 3)", "Encoding": "UTF-8", "Language": "en-US", "VignetteBuilder": "knitr", "URL": "https://github.com/yelleKneK/BUCSS,\nhttps://yelleKneK.github.io/BUCSS,\nhttps://designingexperiments.com", "BugReports": "https://github.com/yelleKneK/BUCSS/issues", "Config/testthat/edition": "3", "RoxygenNote": "7.3.2", "Repository": "https://yelleknek.r-universe.dev", "Date/Publication": "2026-07-30 01:29:47 UTC", "RemoteUrl": "https://github.com/yelleknek/bucss", "RemoteRef": "HEAD", "RemoteSha": "4c511c43bc81c8b2638569d4b3540408da36b550", "NeedsCompilation": "no", "Packaged": { "Date": "2026-10-13 10:48:16 UTC", "User": "root" }, "Author": "Ken Kelley [aut, cre] (ORCID: ),\nSamantha F.

The vignette explains why the test\nof a correlation is not a fixed-predictor regression slope (a correlation study\nsamples both variables, so the statistic follows a chi-square mixture of\nnoncentral F distributions rather than a single noncentral F), gives the rule\nfor when ss_buc_correlation() versus ss_buc_reg_coef(p = 1) applies, and shows\nthe assurance and alpha_prior levers on a correlation plan.\n\nIt then audits the plan with ss_buc_sensitivity() and reads its two attainment\nrates: attainment_with_refusals, which the assurance guarantee is about and\nwhich lands near the requested assurance, and attainment among issued plans,\nwhich a researcher actually experiences; the gap between them is the refusal\nrate and is the visible price of a method that declines rather than guesses. A\nsecond call varies the assumed truth downward, the case a cautious planner most\nwants to see.\n\nRegistered in _pkgdown.yml and noted in NEWS. The vignette builds under R CMD\ncheck, spell check is clean, and no numeric behavior changed (684 tests,\n2598-case grid identical, 17 example ceilings with 0 mismatches).\n", "time": 1785374987 },
