TABLE III.
Effect sizes (Cohen's d) for the statistically significant differences between the HASPI w2 and HASPI v2 accuracy for scores averaged over listeners and repetitions. The RMS error and correlation differences are the average of 10 000 bootstrap replications of the differences in the model outputs, and significance was computed from the bootstrapped confidence intervals. Differences at the 5% level are indicated using one asterisk while differences at the 1% level are indicated by two asterisks. The effect sizes were computed from the bootstrapped means and standard deviations.
