WebThe paper that coined the term p-hacking is online, and an interesting read. TL;DR: P-hacking is the use of data mining to find patterns in data that can be presented as statistically significant, without first devising a specific hypothesis as to the underlying causality. Then a hypothesis is constructed that matches the previously found data. WebApr 21, 2024 · Simonsohn et al. (2014) suggested that it is possible to detect the use of dumb p-hacking methods by means of p-curve plots. Repeated sampling and the use of covariates produce markedly left-skewed (monotonic decreasing) p-curves. Schimmack (2024) noted that left-skewed p-curves are actually very rare. Figure 1 shows the p-curve …

After developing a statistical method to detect this effect, we apply it to our data and find (across several specifications) little to no evidence for 𝑝 ...

WebMay 16, 2024 · Power can be quite low, depending crucially on the particular -hacking strategy and the distribution of actual effects tested by the studies. We relate the power of the tests to the costs of -hacking and show that power tends to be larger when -hacking is very costly. Monte Carlo simulations support our theoretical results.

WebDownloadable! We theoretically analyze the problem of testing for p‐hacking based on distributions of p‐values across multiple studies. We provide general results for when such distributions have testable restrictions (are non‐increasing) under the null of no p‐hacking. We find novel additional testable restrictions for p‐values based on t‐tests. list of kawasaki motorcyclesWebCompute a p-value: this is the probability of seeing the observed effect amongst the null data, in other words, by chance. We do this through repeated simulation of the null data. In our case, we shuffle the ‘date’ labels of the data many times and simply count the occurrence of our test statistic as it appears through multiple simulations. imcdb halloween killsWebJoin the Econometric Society Mailing List.
