 Comparative cp-laws which are not restricted by an exclusive cp-clause are also called unrestricted comparative cp-laws. They assert an invariant connection between an \(X\)-increase and an \(Y\)-increase for all possible values of \(X\) and of the \(X\)-independent remainder variables \(Z_1 ,\ldots ,Z_n\). Unrestricted probabilistic comparative cp-laws have been suggested as an explication of generic causal relations (Cartwright 1989, 145f; Eells 1991, 85f): they assert that a variable \(X\) is a probabilistic cause of some other variable \(Y\) in all possible circumstances, where these circumstances are expressed in terms of the values of \(X\) and the \(X\)-independent remainder variables \(Z_i (1\le i\le n)\).
