Experiments at three levels second-order model

4 Experiments at three levels second-order model 

It is possible to fit zero-, one-, two-, and three-parameter models to the data shown 

The subscript on the parameter P, is used to indicate that it is associated with the coefficient corresponding to Ci times c, that is or This notation anticipates 

Although the fit will be perfect and there will be no residuals, we will 

Let us assume we have a prior estimate of o. We will now rewrite the matrix and consider its meaning in terms of the variances and covariances of the parameter estimates.
