Web25 Oct 2024 · The function topTags will adjust those p-value with method such as 'BH', and after that, it will provide you with the differentially expressed genes with FDR smaller than the threshold that you set (but somehow it's 'p.value' here, instead of 'FDR' ~~~). So the FDR here is the same as adjusted p-value here. WebThe p -values that deviate from this straight line then should correspond to the false null hypotheses. This idea was later developed into an algorithm and incorporated the estimation of into procedures such as Bonferroni, Holm or Hochberg. [8] This idea is closely related to the graphical interpretation of the BH procedure.

The Benjamini–Hochberg method begins by … WebThe p-value is a measure of how likely you are to get this compound data if no real difference existed. Therefore, a small p-value indicates that there is a small chance of getting this data if no real difference existed and therefore you decide that the difference in group abundance data is significant. Web16 Jul 2024 · The p value, or probability value, tells you how likely it is that your data could have occurred under the null hypothesis.
