The average performance Regularized t-test minus the corresponding performance of Welch t-test on the simulated data with varied variance σ₂, where n₁ + n₂ ≡ 60 and σ₁ ≡ 0.5. The average Precision Rate and Recall Rate of Regularized t-test minus that of Welch t-test on the simulated data with varied variance σ₂, where σ₁ ≡ 0.5 and n₁ + n₂ ≡ 60.
