Steven N. Goodman and
Jesse A. Berlin
15 March 1995 | Volume 122 Issue 6 | Page 478
TO THE EDITOR:
In the article by Goodman and Berlin [1], the second sentence of the first full paragraph on page 202 should have read "The power of an experiment is the pretrial probability of all significant outcomes taken together (under a specified alternative hypothesis), and any attempt to apply power to a single outcome is problematic".
