In the Evaluate Design report, the Estimation Efficiency section provides a table of efficiency measures.
Term
The terms included in the model.
Fractional Increase in CI Length
The length of a parameter’s confidence interval as given by the current design compared to the length of such an interval given an ideal design. See Fractional Increase in CI Length. Smaller values are better.
Relative Std Error of Estimate
The ratio of the standard deviation of a parameter’s estimate to the error standard deviation. This value indicates how large the standard error of each parameter estimate is, relative to the error standard deviation. See Relative Standard Error of Estimates. Smaller values are better.
