Polynomial contrast analysis

WebFurthermore, when orthogonal polynomial contrast coefficients were investigated, linear effects were found significant (P < 0.01) and cubic effects were obtained significant (P < 0.05), but quadratic effect was obtained insignificant (P > 0.05). Key words: Analysis of variance (ANOVA), comparisons, Dunnett’s test, contrast, trend analysis. 1. Webin order to render (1.2) unambiguous. This complicates the analysis, and we return to such a general scenario only episodically. In contrast, if all c j are positive integers, W becomes a polynomial of degree c= P p j=1 c j and (1.2) extends to the whole complex plane C. This is the situation of our primary concern.
