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. 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).

WebIt is a dose-response study that is a completely randomized design with four doses of alcohol plus a control group. This chapter does a full analysis of this data set, employing many of the methods outlined in earlier chapters. Evaluation of the shape of the does response function is addressed with the use of Orthogonal Polynomial contrasts. WebIn testing the within-subjects effects, an orthonormal transformation is automatically performed on the dependent variables in a repeated measures analysis. The contrast for each within-subjects factor is entered after the number of levels. If no contrast keyword is specified, POLYNOMIAL(1,2,3...) is the default.
