| Summary : Mixed Level Response Surface Designs
|
Description :
Response Surface Designs (RSDs) involving factors not all at same
levels are called Mixed Level RSDs (or Asymmetric RSDs). In many
practical situations, RSDs with asymmetric levels will be more suitable
as it explores more regions in the design space. (J.S. Mehta and M.N.
Das (1968) < doi:10.2307/1267046>. \"Asymmetric rotatable designs and
orthogonal transformations\").This package contains function named
ATORDs_I() for generating asymmetric third order rotatable designs
(ATORDs) based on third order designs given by Das and Narasimham
(1962). Function ATORDs_II() generates asymmetric third order rotatable
designs developed using t-design of unequal set sizes, which are
smaller in size as compared to design generated by function ATORDs_I().
In general, third order rotatable designs can be classified into two
classes viz., designs that are suitable for sequential experimentation
and designs for non-sequential experimentation. The sequential
experimentation approach involves conducting the trials step by step
whereas, in the non-sequential experimentation approach, the entire
runs are executed in one go (M. N. Das and V. Narasimham (1962)
< doi:10.1214/AOMS/1177704374>. \"Construction of Rotatable Designs
through Balanced Incomplete Block Designs\"). ATORDs_I() and
ATORDs_II() functions generate non-sequential asymmetric third order
designs. Function named SeqTORD() generates symmetric sequential third
order design in blocks and also gives G-efficiency of the given design.
Function named Asymseq() generates asymmetric sequential third order
designs in blocks (M. Hemavathi, Eldho Varghese, Shashi Shekhar and
Seema Jaggi (2020) < doi:10.1080/02664763.2020.1864817>. \"Sequential
asymmetric third order rotatable designs (SATORDs)\"). In response
surface design, situations may arise in which some of the factors are
qualitative in nature (Jyoti Divecha and Bharat Tarapara (2017)
< doi:10.1080/08982112.2016.1217338>. \"Small, balanced, efficient,
optimal, and near rotatable response surface designs for factorial
experiments asymmetrical in some quantitative, qualitative factors\").
The Function named QualRSD() generates second order design with
qualitative factors along with their D-efficiency and G-efficiency.
The function named RotatabilityQ() calculates a measure of rotatability
(measure Q, 0 < = Q < = 1) given by Draper and Pukelshiem(1990) for given
a design based on a second order model, (Norman R. Draper and Friedrich
Pukelsheim(1990) < doi:10.1080/00401706.1990.10484635>. \"Another look at
rotatability\").
