In many practical situations, RSDs with asymmetric\nlevels will be more suitable as it explores more regions in the\ndesign space. (J.S. Mehta and M.N. Das (1968)\n. \"Asymmetric rotatable designs and\northogonal transformations\").This package contains function\nnamed ATORDs_I() for generating asymmetric third order\nrotatable designs (ATORDs) based on third order designs given\nby Das and Narasimham (1962). Function ATORDs_II() generates\nasymmetric third order rotatable designs developed using\nt-design of unequal set sizes, which are smaller in size as\ncompared to design generated by function ATORDs_I(). In\ngeneral, third order rotatable designs can be classified into\ntwo classes viz., designs that are suitable for sequential\nexperimentation and designs for non-sequential experimentation.\nThe sequential experimentation approach involves conducting the\ntrials step by step whereas, in the non-sequential\nexperimentation approach, the entire runs are executed in one\ngo (M. N. Das and V. Narasimham (1962)\n. \"Construction of Rotatable\nDesigns through Balanced Incomplete Block Designs\"). ATORDs_I()\nand ATORDs_II() functions generate non-sequential asymmetric\nthird order designs. Function named SeqTORD() generates\nsymmetric sequential third order design in blocks and also\ngives G-efficiency of the given design. Function named\nAsymseq() generates asymmetric sequential third order designs\nin blocks (M. Hemavathi, Eldho Varghese, Shashi Shekhar and\nSeema Jaggi (2020) .\n\"Sequential asymmetric third order rotatable designs\n(SATORDs)\"). In response surface design, situations may arise\nin which some of the factors are qualitative in nature (Jyoti\nDivecha and Bharat Tarapara (2017)\n. \"Small, balanced,\nefficient, optimal, and near rotatable response surface designs\nfor factorial experiments asymmetrical in some quantitative,\nqualitative factors\"). The Function named QualRSD() generates\nsecond order design with qualitative factors along with their\nD-efficiency and G-efficiency. The function named\nRotatabilityQ() calculates a measure of rotatability (measure\nQ, 0 <= Q <= 1) given by Draper and Pukelshiem(1990) for given\na design based on a second order model, (Norman R. Draper and\nFriedrich Pukelsheim(1990)\n. \"Another look at\nrotatability\").", "License": "GPL (>= 2)", "Encoding": "UTF-8", "RoxygenNote": "7.2.3", "NeedsCompilation": "no", "Packaged": { "Date":
