Table 1. Linear cell variation (LCV) values for the five test cases described in §3.

This quantity, introduced in §2.2 and detailed in Appendix A , is a quantitative measure of data-set isomorphism in a manner somewhat complementary to that described by dendrograms. An LCV value of 0 indicates perfect isomorphism. The larger the value of LCV, the higher the non-isomorphism among the data sets being considered.

Test case	LCV (%)
