The use of the Gini index in Design of Experiments is unexplored. We present here some connections between the aberration of a fractional factorial design and the Gini concentration index of the fraction terms. In fact, both the aberration and the Gini index depend on geometrical properties of the fraction. The main tool in our theory is the...

Given a multivariate complex centered Gaussian vector Z = (Z1, . . . , Zp) with non-singular covariance matrix S, we derive sufficient conditions on the nullity of the complex moments and we give a closed-form expression for the non-null complex moments. We present conditions for the factorisation of the complex moments. Computational...
