WebFeb 9, 2024 · Based on the observed value (£500K and £800K), we found out the corresponding p-values i.e. the likelihood of getting this observation in the population distribution. We compare the p-value with our pre-decided Alpha levels. Only two possibilities… 1. Observed P-Value ≤ Alpha: WebThe BH properties hold regardless of the number of p-values, while qvalue is asymptotic, so the BH approach is more robust than qvalue when the number of hypotheses being tested isn't very large.

qvalue: Q-value estimation for false discovery rate control

WebA p-value threshold (alpha) of 0.05 yields a FPR of 5% among all truly null features. A q-value threshold of 0.05 yields a FDR of 5% among all features called significant. The q … WebA limitation of Cochran’s Q test is that it might be underpowered when few studies have been included or when event rates are low. Therefore, it is often recommended to adopt a higher P-value (rather than 0.05) as a threshold for statistical significance when using Cochran’s Q test to determine statistical heterogeneity. 30, 36: I 2 index
