I've been developing my probabilistic modeling capabilities this year at work, so in my free time I thought it'd be a fun exercise to write an article about modeling MLB win probabilities using a Bayesian Hierarchical model with Stan. If this interests you, then give it a whirl! If not, then just pretend to read it and tell me I did great!! https://lnkd.in/gbwvJDxw #Stan #BayesianStatistics

Wow, great post! Especially since it confirms my prior that the Braves were terribly unlucky. I do think the sequencing of hits makes a huge difference. Perhaps even just accounting for variability of hard-hit% across the order would be helpful. When team has high variability, then there are a few players hitting much better, making it harder to sequence hits or hit with runners on? Just a thought.

Hey Derek you did great!!! Maybe I'll read later.

Interesting data Derek! Slightly consoling to read after the Brewers wildcard loss last week.

Hello. I do not know you but I can tell you’re extremely intelligent/educated. However, the problem with analytics in the game of baseball is that they do not measure “anything” that truly matters. I am very analytical and understand that “numbers don’t lie.” However, they do not measure what makes a hitter, pitcher, fielder, coach etc a winner, productive athlete, successful, etc. If you or anyone that reads this would like to understand more of what I’m talking about…..feel free to reach out. I would absolutely have no problem learning from you as long as you’re willing to listen to what I know, have lived, learned, and “done.” I also somewhat understand high level math too. Appreciate the post 👊🏼
