he modified t test applied to the prostate cancer data. ‘rho’ stands for the
coefficient. (a) The correlation between raw (original) base two logarithm of
e and the estimated base two logarithm of fold change from a limma model. (b)
tion between the original t test p values and the SAM t test p values.
6.2 shows the confusion matrix for comparing the t test and the
t test results, where the critical p value was 0.01. This analysis
at two approaches still had some degrees of discrepancy and

Two tests generated results which are significantly different.
