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. WebObjective. Our goal is to obtain a polynomial regression model of order k such that. We can accomplish this by using orthogonal contrast coefficients. where p j (x) is a polynomial of …
