Hi, I have not been able to find R tools that permit an orthogonal polynomial ANOVA analysis: single degree of freedom F-test comparisons including L, Q, C, etc. terms. Do such tools exist?
I guess you can accomplish something similar by doing straightforward polynomial regression and removing powers manually, combined with ANOVA model comparisons.
