Figure 22.3 Fit Life by X Model for Prior Data
The model for the mean is given in the Estimates outline. The Estimate column contains the parameter estimates for the intercept (β0), the linear coefficient (β1), and the scale (σ). The estimated variances and covariances for the parameter estimates are given in the Covariance Matrix outline. Use these parameter estimates and their covariances as your prior values when you construct your ALT design.
