What basis is confidence calculated on?
ddn opened this issue · 2 comments
In looking at the confidence calculations, I noticed it is not calculated in the same way as explained here:
For example, for the same data set genetify gives me a .496 vs a .749 p-value.
Can you point me to any links on what the basis is? I found this http://faculty.vassar.edu/lowry/fcall.js and poked around, but I can't say I understood it.
Greg, I know this is a mostly dead project for you so feel free to ignore. Hopefully someone interested will notice the activity and jump on board.
Genetify uses a f-test to determine differences between n groups on a continuous variable. See http://en.wikipedia.org/wiki/F_statistic . The blog article describes a binomial test. The f-test is more general but less powerful -- should be lower confidence on the same data.
