- ~~Twitter user @MOCallanain highlighted that the predicted tie rate is < ~0.2, when in actuality it's higher. Likely due to teams playing for loser point, can we parameterize the model to include a tie boost? Diagonal enhanced metric should work - calculate like the DC 0/1 goal enhancement. Model currently re-scales to increase odds to a reasonable amount.~~ DONE
Currently, only scores are used for model generation. Moneypuck has an expansive expected goals model available for download and updated regularly (see http://moneypuck.com/data.htm). Deriving the team performance by expected goals instead of actual could reduce the impact of luck on expected future performance.Won't Do - Use my own xG model instead (see BulsinkBxG).Switch to NHL API for scores and scheduleDONE- ~~Twitter user @joseph__ii picked up on a quirk of the OT/SO odds assignment (see https://twitter.com/joseph__ii/status/1357785234285109248). Try rebalance with league or teams' OT performance measure? ~~ DONE
