Really thorough statistical analysis of Anki (flashcard app) data

rpubs.com/rain8/1100036 Its a work in progress with only two steps finished. Not exactly an addon because its in R not Py. So far the project does many little things like find bugs in user’s collection, describe the growth of their collection and text mining. Ultimate goal is to hopefully be able to use anki as continuous cognitive tester and allow users to learn about and optimize their memorization process. Instructions to run on your own data : github 

I am not sure data in anki could really be used as a continuous cognitive health test. Probably requires removing lots of artifacts and other influences and then finding outside influence that definitely relates to cognition.  Lit review.
