Dummy variables in plackett burman design
WebPlackett-Burman design selects only the significant few from the lot, based on the degree of influence (significance). A situation where you can only say yes or no does not really … Webdesign such as Plackett–Burman design and RSM. Plackett–Burman design determines the most impor-tant variables for further optimization and provides unbi-ased estimates of linear of all variables with maximum ac-curacy for a given number of observations [20], whereas, RSM optimize all the affecting parameters collectively [22].
