    Looks very interesting. I hope we can get a copy of the presentation.

  2. Stan Young led a great seminar this afternoon. He had us toss 10-sided dice to demonstrate the ease of generating statistical significance by chance–if you allow multiple testing and report just the stat sig ones. Spurious p-values, in short. I’ll post his slides tomorrow.

      Maybe this was covered in the lecture, but doesn’t this dice demonstration miss the point about base rates bought up in the Ioannidis paper (and elsewhere)?

      In my opinion, multiple comparisons also tend to get overemphasized in bioinformatics to the detriment of other issues such as power considerations and effect overestimation.

      In many bioinformatics applications such as gwas and differential expression analysis, multiple comparison adjustments might be considered a roundabout way to account for low base rates without actually modeling them.

  3. There are lots of ways that an experiment can come to grief, fail to replicate. Asking lots of questions and not taking multiple comparisons into account is just one problem. Dealing with multiple questions is largely a solved technical problem, Westfall and Young, 1993. Independent replication is the experimental way forward.

I welcome constructive comments that are of relevance to the post and the discussion, and discourage detours into irrelevant topics, however interesting, or unconstructive declarations that "you (or they) are just all wrong". If you want to correct or remove a comment, send me an e-mail. If readers have already replied to the comment, you may be asked to replace it to retain comprehension.
