chiSqStat
~~This function returns the chi-sq statistic (which is compared to a reference
Chi-sq distribution) for the chi-sq approximation of npGSEA
for
a corresponding GeneSet
or a list of these statistics for a GeneSetCollection
.
This method is applicable for only the chi-sq approximation method.
