  1. aProportion of corrected variance (i.e., percentage of total variance in the score introduced by each facet), when negative variances are rounded to 0
  2. bThis source of variance includes variance linked to the interaction of all the facets (R × I × O:B), as well as the unidentified residual variance (e). See text for further details
