Changing the Bayes scores didn't have an impact on accuracy with newly-generated
scores. This doesn't say that changing the scores with what was previously
generated does not impact accuracy (we know otherwise).
Do you really want me to generate the scores again? It's a real ballache but
I'll do it.
Samples: vm-set1-2.0-4.0-100-nobob vm-set1-2.0-4.0-100-nobob-ib
False positives:
Sample 1: mean=0.0554% std=0.0229
Sample 2: mean=0.0595% std=0.0252
Statistically significantly different with confidence 99.2161%
Estimated difference: -0.0041% +/- 0.0117
False negatives:
Sample 1: mean=3.3473% std=1.1779
Sample 2: mean=3.3299% std=1.1745
Not statistically significantly different (alpha=0.9500)
Estimated difference: 0.0174% +/- 0.1339
TCR (lambda=50):
Sample 1: mean=17.2267 std=6.1150
