Instance Attribute Details

#delta_presence_estimation_histogram ⇒ Array<Google::Privacy::Dlp::V2::AnalyzeDataSourceRiskDetails::DeltaPresenceEstimationResult::DeltaPresenceEstimationHistogramBucket>

Returns The intervals [min_probability, max_probability) do not overlap. If a value doesn't correspond to any such interval, the associated frequency is zero. For example, the following records: 0, max_probability: 0.1, frequency: 17 0.2, max_probability: 0.3, frequency: 42 0.3, max_probability: 0.4, frequency: 99 mean that there are no record with an estimated probability in [0.1, 0.2) nor larger or equal to 0.4.

class DeltaPresenceEstimationResult
  # A tuple of values for the quasi-identifier columns.
  # @!attribute [rw] quasi_ids_values
  #   @return [Array<Google::Privacy::Dlp::V2::Value>]
  #     The quasi-identifier values.
  # @!attribute [rw] estimated_probability
  #   @return [Float]
  #     The estimated probability that a given individual sharing these
  #     quasi-identifier values is in the dataset. This value, typically called
  #     δ, is the ratio between the number of records in the dataset with these
  #     quasi-identifier values, and the total number of individuals (inside
  #     *and* outside the dataset) with these quasi-identifier values.
  #     For example, if there are 15 individuals in the dataset who share the
  #     same quasi-identifier values, and an estimated 100 people in the entire
  #     population with these values, then δ is 0.15.

  # A DeltaPresenceEstimationHistogramBucket message with the following
  # values:
  #   min_probability: 0.1
  #   max_probability: 0.2
  #   frequency: 42
  # means that there are 42 records for which δ is in [0.1, 0.2). An
  # important particular case is when min_probability = max_probability = 1:
  # then, every individual who shares this quasi-identifier combination is in
  # the dataset.
  # @!attribute [rw] min_probability
  #   @return [Float]
  #     Between 0 and 1.
  # @!attribute [rw] max_probability
  #   @return [Float]
  #     Always greater than or equal to min_probability.
  # @!attribute [rw] bucket_size
  #   @return [Integer]
  #     Number of records within these probability bounds.
  # @!attribute [rw] bucket_values
  #   @return [Array<Google::Privacy::Dlp::V2::AnalyzeDataSourceRiskDetails::DeltaPresenceEstimationResult::DeltaPresenceEstimationQuasiIdValues>]
  #     Sample of quasi-identifier tuple values in this bucket. The total
  #     number of classes returned per bucket is capped at 20.
  # @!attribute [rw] bucket_value_count
  #   @return [Integer]
  #     Total number of distinct quasi-identifier tuple values in this bucket.
