Léo VarnetHello <a href="https://qoto.org/tags/statstodon" class="mention hashtag" rel="nofollow noopener" target="_blank">#statstodon</a>! A reviewer asks me to perform a post-hoc <a href="https://qoto.org/tags/PowerAnalysis" class="mention hashtag" rel="nofollow noopener" target="_blank">#PowerAnalysis</a>. I know this is generally not advised because if you replace the a priori effect size by the effect size measured in the experiment, this will introduce an erroneous relationship between the significance level of the test and the measured power. … but does that mean that there is no proper way of measuring power retrospectively? For example, if you refrain from using the measured effect size and instead simulate a range of “a priori” effect size unrelated to the results of the test, then the dependency of the power to the significance level should not happen? <a href="https://qoto.org/tags/stats" class="mention hashtag" rel="nofollow noopener" target="_blank">#stats</a> <a href="https://qoto.org/tags/statschat" class="mention hashtag" rel="nofollow noopener" target="_blank">#statschat</a> <a href="https://mastodon.social/@lakens" class="u-url mention" rel="nofollow noopener" target="_blank">@lakens</a>
