Confusion matrix / advanced incorrect statistics


#1

Are there any third party apps out there that track what incorrect answers you’ve given, and compile cool statistics based on that?

Realize this isn’t a simple app to write, since the data isn’t available through the API (I think) so any app would have to collect this data during reviews and store it.

Would be cool to see, for example:

  • Which pairs of words you often confuse with each other
  • Which rendaku you never remember / remember too often
  • Which radicals you frequently mess up

Some of this can probably be inferred with ordinary statistics too - is anything like this available?

It’s not as sophisticated as what you’re asking for, but the Leech Detector at least lets you know what ones you’re getting wrong a lot: https://s3-us-west-2.amazonaws.com/wktoys/leechDetector.htm
