Regression-based (Masto et\nal., 2008, ), Principal\nComponent Analysis-based (Andrews et al., 2004,\n), Fuzzy Logic, Entropy Weighting\n(Shannon, 1948, ), and\nTOPSIS (Hwang and Yoon, 1981, ).\nImplements four variable scoring functions: more-is-better,\nless-is-better, optimum-value, and trapezoidal, following\nKarlen and Stott (1994, ).\nIncludes automated Minimum Data Set selection via Principal\nComponent Analysis with Variance Inflation Factor filtering\n(Kaiser, 1960, ), one-way ANOVA\nwith Tukey HSD post-hoc tests, leave-one-out sensitivity\nanalysis, and publication-quality visualization using\n'ggplot2'.", "License": "GPL (>= 3)", "Encoding": "UTF-8", "Language": "en-US", "LazyData": "true", "LazyDataCompression": "xz", "RoxygenNote": "7.3.3", "VignetteBuilder":
