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. WebThe POLYNOMIAL option in the REPEATED statement indicates that the transformation used to implement the repeated measures analysis is an orthogonal polynomial transformation, and the SUMMARY option requests that the univariate analyses for the orthogonal polynomial contrast variables be displayed. http://www.discoveringstatistics.com/docs/contrasts.pdf teams first time
