                        boolean ignoreNaNs)

      Description copied from interface: `Dataset`
      Calculate residual of dataset with object o and weight. The weight is used to multiply the squared differences
      Specified by:
        `residual` in interface `Dataset`
      Overrides:
        `residual` in class `BooleanDatasetBase`
        `ignoreNaNs` - if true, skip NaNs
      Returns:
