I believe however, this is implausible as each field has a small number of favorite error control methods. You could use simulated data to quantify the agreement over different software under the null. | |
Jul 5, 2013 at 9:11 | comment | added | Arun | The problem is that the reason they go for different softwares is that there's normally a huge non-overlap between these softwares (meaning the correlation will be typically low). This is also my experience with these softwares on my data. But I choose one and fetch results conservatively. I am beginning to get the feeling that, in those cases, from what you and January point out, it'll most definitely fail...? | |
