With the help of LLMs, I have partially solved a long-troublesome issue with GBDTs!

@kjhogo I never doubted

@EvanMiya just wait til your repliers learn about the birthday paradox!

@lymanstoneky the 17% reduction in mortality is deaths from all causes, not malaria deaths, so the drop in malaria deaths is likely much larger than that

@yolo_pinyato @kmedved (and by coaching changes I mean - adjustments made by the coaches)

[Nathan Walker @bbstats]

OpenRAPM now has "Wins over Starter Average"

Why: When thinking about MVP, who cares about 'replacement player'?

How: Wins Added vs the avg starter this season - reducing minute weight during garbage time, & accounting for player effect on pace

@yolo_pinyato @kmedved (sorry for reiterating what you already said to some degree)

but in my experience - if you just measure player change between RS/playoffs you moreso are measuring coaching changes, player improvement, player injury

@NBA please fix

[Timberwolves Clips @WolvesClips]

Wolves Fans:

For the first time in 7 years of posting video clips, I received a copyright complaint from the NBA on the clips posted last night

If you have found @WolvesClips to be valuable to your NBA fandom, I’d really appreciate you sharing what this account has meant to you

@yolo_pinyato cursory look suggests the opposite for jokic
are you adjusting for competition?

[Nathan Walker @bbstats]

@yolo_pinyato All good RAPM metrics account for this to some degree. In my testing this isn't really cut and dry. Would be curious to see what your testing showed

@YahooFinance Water - very wet!

the Mahdi is too humble to say he is worth $2 trillion

even more reason to know that he is!

@MZavagno11 @blouisz24 "winning minutes " is rather noisy, especially early

[Nathan Walker @bbstats]

@MZavagno11 @blouisz24 OpenRAPM is single season fwiw
