Daily Leaderboard Metrics Question
Joakim Arvidsson (Cream Mongoose)

Contest

Hi Q Folks,

Thanks for fixing the cvs download with all the risk and performance metrics. Very interesting to analyse!

I'm curious though how it's possible for so many of the entries to go above (and below), sometimes by a lot, many of the contest requirement boundaries? I've had my algos automatically withdrawn several times for only just slightly breach one of the boundaries. Are these outlier 'spikes' and is there a tolerance level for these 'spikes' for all of the contest constraints? Many thanks in advance.

Regards,
Joakim

Also, if it's not too difficult (or something you don't want to disclose), it would be great to also get:

  • Number of days in contest
  • Daily score average
  • Daily score std from mean (and perhaps skew)

Maybe see it as an opportunity for you to teach and encourage us mere mortals to think in terms of basic statistical concepts?
