Defining Models and Prediction Equations Parameter In most cases of least squares fitting the model coefficients for previously added terms Estimates change depending on what was successively added. For example the X1 coefficient Don t might change depending on whether or not an X2 term was included in the model. This Change as is not the case when the design is orthogonal as is a 23 full factorial design. For Additional orthogonal designs the estimates for the previously included terms do not change as Terms additional terms are added. This means the ranked list of effect estimates Added simultaneously serves as the least squares coefficient estimates for progressively more complicated models. Yates For convenience we list the sample Yates output for the Eddy current data set here.
