This was one of my first indicators, its also the first indicator i made a preprint paper about, i strongly encourage you to read the paper i made here : hal.archives-ouvertes.fr/hal-02145175/document
Dont be triggered by the lack of quality of the paper, i only did it for fun. I might further develop this preprint thus ending with something more readable.
