| orth_D {ffmanova} | R Documentation |
The function takes the output from modelData as input and calculates adjusted data
orth_D(D, model, method)
D |
A list containing a regressor matrix for each model term |
model |
The model coded as a matrix |
method |
Either "test" or "om" |
The "test" method adjusts data according to Type II* sums of squares. This is an extension of the traditional Type II method. The "om" method orthogonalises terms according to the model hierarchy. The result is a non-overparameterised representation of the model.
An adjusted version of D is returned.
