Hi Irene,

» Thank you for your explanation.

You are welcome. A picture tells more than a thousand words (AUC only). ;-)


The PE and its CI of T/R are similar. The small bias is caused by the fact that the average PE of S/R and T/S (\(\sqrt{141.09\times83.12}\)) is close to the T/R with 116.05. The other comparisons show negative biases. The CI of S/R is narrower in the pooled model and the CI of T/S is wider.
We don’t want to go there.
