Goal

  • Refactor API such that we can do calculate separately and pass these as input to our API
    • If the stats are not passed as input, then we recalculate internally.
    • If they are already input, then they are good!

Basic Implementation

  • extend DlFieldProfile so that we can store more statistic like ones below

Stats

  • Number of potential outliers

  • Entropy (for measuring uniformity)

    • Easy -- just call dl.entropy

  • Number of Unique Values (We already got this from dl.profile)

Rank by Feature http://ieeexplore.ieee.org/document/1382892/

(RBF)

  • Normality
  • Size of the biggest gap
