RE: st: RE: exact (more decimals) p values ?
In my experience, the need for extra decimal places in P-values is
usually motivated by multiple comparisons. For instance, if you are
doing a genome scan of 10,000 polymorphism associations, then, on
average, one of these polymorphism associations will have a sample
P-value of P<=0.0001, even if all corresponding population
associations
are zero.
This is my experience too. We do genome scans against microarray
phenotypes, so multiplicity of tests becomes ridiculous. There should
be some option to display p values in scientific notation.
