Yeast data: Imputation via the database is always better than imputation within logical sets. Each vertical line represents a logical set; the top of the line is mean RMSE of imputation within the set, and the bottom of the line is mean RMSE of imputation via the database. Some logical sets have the same numbers of columns (the horizontal axis), and their lines are drawn with slight offsets so that they do not overlap.
