Use of asymmetrical factorials for generating designs for quadratic mixture model
Mclean and Anderson (1966), Snee (1975) and Nigam et al. (1983) have used symmetric factorials for constructing designs for fitting the quadratic mixture models, when the mixture components are constrained by upper and lower bounds. In this paper, we have used asymmetrical factorial plans for constructing these designs.
