Despite limited statistical power (2017)


A great short post by Andrew Gelman HERE.

It’s not always clear what people mean by this expression, but sometimes it seems that they’re making the “What does not kill my statistical significance makes it stronger” fallacy, thinking that the attainment of statistical significance is a particular feat in the context of a noisy study, so that they’re (mistakenly) thinking of the “limited statistical power” of that study as a further point in favor of their argument.
