What are my options for conducting any sort of power analysis post hoc? And if not a post hoc power analysis, what should I report? …

However, one of the persons that is reviewing my analysis says that I should also perform a post-hoc power analysis for this study, considering also the little difference between the two cut-offs (the … I have read about the fact, and probably you will confirm it, that performing a post-hoc power analysis is not considered correct, but I have to do it. Is it correct to use this formula? …

I've read that post-hoc power analysis is useless when the result of a test is statistically insignificant, which I understand (post-hoc power analysis is just circular logic in this scenario). … Subsidiary question: are there situations where it wouldn't be justified to run post-hoc power analysis after finding a significant result? …

However, at the end, the website cautions: The Dangers of Post-Hoc Analysis Post-hoc power analysis has been criticized as a means of interpreting negative study results.2 Because post-hoc analyses are … typically only calculated on negative trials (p ≥ 0.05), such an analysis will produce a low post-hoc power result, which may be misinterpreted as the trial having inadequate power. …

As part of my analysis result I want to report the post-hoc power for each predictor. … However, post-hoc power analysis in Stata (and other softwares I know) is done assuming the data is generated through a simple random sampling. …

【What I do not want】:(Please read carefully): Criticism of the "post-hoc power" is no thank you !! This is not a place to criticize the"" post-hoc power." … (My question4): In the following 【My Experiment】, does 【My Code】 calculate the post-hoc power of Equation 1? …

My thinking is that maybe a post hoc power analysis might tell me something useful. SPSS spits out an observed power of 0.69. At this point I am lost. Does the observed power tell me anything useful? …

“Correct post-hoc analysis” I said is synonymous with “post-hoc analysis that many people criticize.” My Question What is the post-hoc power in the following experiment? … = NULL, alternative = c("two.sided")) Which is the “correct” post-hoc power calculation code? …

I was wondering whether I need to adjust my alpha when testing the power of effects for which I have adjusted for multiple testing. … Now, I would like to do a post hoc power simulation via simr. Do I also need to set alpha to 0.05/8 ? …

Now, there is a significant pred1 fixed effect (p< .001), and I was asked to preform a post hoc power analysis arguing that 17 L2 groups do not yield acceptable power. … Questions: Does it ever make sense to do post hoc power analysis, for either significant or insignificant results? …

analysis - designed experiments, I modified that R code to perform post-hoc power analysis. … In this post-hoc power analysis I assume that the rates estimated from the observed data are true. repetitions = 10 significant = matrix(nrow=repetitions, ncol=3) for(i in 1:repetitions){ final_rep …

We have posts on here discussing why post hoc power calculations are flawed. What about post hoc calculations of the effect size that we could catch? That seems logically equivalent. … If I were to flip the problem around to have an effect size of interest, say $0.3$, and calculate that we have $90\%$ power to detect such a difference, that seems like an invalid post hoc power calculation …

I have been asked by my supervisor to provide a post-hoc power analysis and don't understand which method to use, given I know the population, and the cases. …

Based on post-hoc analysis, I had 89% power to detect this effect. But I am unsure about sample size. Someone might say it's too small for a study with a 3-way interaction. … Now, can I simply report the post-hoc power analysis in a paper and claim that it's ok? …
