Abstract

In the present chapter, the symmetry of form invariance, introduced in Chap. 6, is generalised to a discrete event variable x. It was assumed in Chap. 6 that both x and the hypothesis parameter ξ were real. If x is discrete and ξ is real, form invariance cannot exist in the sense of (6.21), because there is no transformation of x that can take account of an infinitesimal transformation of ξ. Hence the definition of form invariance given in Chap. 6 does not cover the case of discrete x. The linear representation (8.20) of form invariance found in Chap. 8 provides the starting point for the more general definition.
