This mode is used to perform univariate feature selection with T-Test. We compare each feature individually for evidence of differential distribution in the two prediction classes. If the T-Test p-Value is less than the confidence interval, then the feature is selected as an informative biomarker.

It is implemented by org.bdval.DiscoverWithTTest.java.
