On the Algebraic Structures in the Construction of Confounding Plans in Mixed Factorial Designs on the Lines of White and Hultquist
沿 White 与 Hultquist 方法构造混合析因设计混杂方案的代数结构
White and Hultquist (1965) developed a method of combining finite fields mapped into a finite commutative ring to provide confounding plans for mixed factorial experiments where the numbers of the levels of factors have to be prime or the power of a prime. This paper extends their procedure to cover mixed factorials where the numbers of levels of factors need to be relatively prime, and not necessarily all prime, thus covering a wider range of mixed factorial experiments…
