[BioC] Multtest Question!

[Puhong Gao]

Hi, all,

In the documentation of the Multtest R package, the raw p values were generated based on the standard Gaussian distribution. Can someone explain to me why it should be like that? What situations can it be applicable to? The p values based on the standard Gaussian distribution are much smaller than those based on the t-distributions. The consequence of this is more genes will be picked up as significant. How can this be explained? Your inputs will be very appreciated.

Have a great day,
