Another use of ANCOVA is to adjust for preexisting differences in nonequivalent (intact) groups. He and Junge were able to produce two such tensor norms that are nonequivalent. The of is the number of distinct (nonequivalent) conjugacy classes. This enables the measurements of quadrupolar doublets for each nonequivalent deuterium atom. All three of those nonequivalent definitions of pointwise continuity are still in use. Most cubanes have more complicated structures, usually with nonequivalent vertices. Reciprocal heterozygotes have a genetically equivalent, but they are phenotypically nonequivalent.
