Missingness (as a percentage of all records) for different probability threshold levels and levels of LOS detail for the quasi-identifiers in the second PUMF for combinations ("comb") and complete algorithms. The last two rows show the percentage of cells in the quasi-identifiers that are suppressed and the entropy change from the baseline as a percentage.
