Type 1 and type 2 errors associated with the WISE hierarchical degradation and resampling tests (O75, O60, O5, O10, and O-RS)

The percentages for each of these risk categories was calculated by weighting by the proportion of composition for the entire dataset by the percentage correct in that particular category (low, medium, high) in order to obtain a percentage error and percentage correct whole-set results. These results represent the aggregate for all entry types (pressure, temperature, and wind) across eight tasks. More details about this experiment can be found in the supplemental information.
