1.
Under Prior Mean, enter the prior acceleration model parameter estimates that you obtained using the Fit Life by X platform with the hypothetical data. Round the values shown in the Estimates outline in Figure 21.3 to two decimal places:
Enter -1.87 for Power (Torque).
3.
De-select the option Ignore prior variance. Generate the local design for the prior mean.
In the row and column for Intercept, click on 0.10000 and type 0.04570.
In the row for Intercept and column for Torque, click on 0.00000 and type -0.01062.
In the row for Intercept and column for scale, click on 0.00000 and type -0.00015.
In the row and column for Torque, click on 0.10000 and type 0.00248.
