Information on phenotypic traits both numerical and categorical (per line)—is displayed as a heat map running alongside the lines.
With his extended version of Aristotelian logic in mind (giving not-X equal billing), he gave (p. 30) a set of three transformation rules which allowed one to construct all valid two-line categorical arguments (providing you accepted the unwritten convention that simple names like X and not-X denoted non-empty classes).
Results of the ANCOVA for differences in the means of cube root body mass and tibia length as a function of the three categorical factors (generation, line and sex), and their interactions.
Each "experiment" was considered a categorical blocking factor, cell line (if different cell lines were used) was a categorical factor (that is, HCC1954 and HCC1954 LTRes), and treatment (that is, IgG vs AIIB2) was a categorical factor, yielding three-way or two-way factorial designs.
One of the most important assumptions to be met in the ANCOVA model is homogeneity of regression slopes (Huitema 2011; Rutherford 2001): that is, for each level of a categorical variable, the regression lines of the dependent variable and a covariate must be parallel.
Participants made categorical semantic judgements about line drawing pictures of common objects, deciding if the objects depicted were large or small (with reference to a shoe box size), manmade or natural (Fig. 1).
Edwin S. Kneedler, a lawyer for the federal government, took the more promising categorical approach, proposing two different lines.
