A note on confidence intervals for the power of t-test

Tarasinska [2005. Confidence intervals for the power of student's t-test, Statist. Probab. Lett. 73, 125-130] proposes a minimum length method for determining confidence interval estimates for the power of the one-sided t-test at fixed alternative means. This note points out the lack of proof for the coverage probability and provides results to indicate that the nominal coverage probability is not achieved.
