zStat
~~This function returns the Z-statistic (which is compared to a reference
standard normal distribution) for the normal approximation of npGSEA
for
a corresponding GeneSet
or a list of these statistics for a GeneSetCollection
.
This method is applicable for only the normal approximation method.
