Thereβs been no footy for the past two months. So Max Barry (β¦@SquiggleAFLβ©) and his mates - @Stattraction, @fuzzybluerain, @aflalytics and @AflLadder - stepped in to create Virtually Season 2020. Ken Hinkley can only dream of a year like this! https://t.co/dHqQQ9nTuh

Port Adelaide is the big winner so far in a virtual season created by analytics experts

I'll have 2 models running for AFLW match predictions: SELO (Scoring ELO) and SELOP (Scoring ELO + Players). The player model uses a moving average of dream team points as a proxy for player quality. I'll be using SELOP for live win prob and running sims.

Something I've been looking at for a while and finally got around to posting! Some words, equations and graphs on modelling home ground advantage in AFL, including a look at venue dimensions and club membership figures. https://t.co/q7DuLHcCis

I'm looking for someone to scrape sports data...possibly several projects if work is good/affordable. Includes AFL Tables, but more @ESPNcricinfo and Sports-Reference. Any recommendations? @insightlane @MatterOfStats @TheArcFooty @SquiggleAFL @AFLLab @GRAFTRatings @AFLalytics

That's a wrap for 2019, after a rocky start to the year it ended pretty well for the AFLalytics model: On @SquiggleAFL: 1st in bits, 3rd in MAE, 10th in tips. On Monash: 1st in Gaussian, 2nd in bits, 16th in Normal. Congrats to all the tippers and all the best for 2020!

Is an AFL team coming off the bye disadvantaged? Some believe this to be true. But as human beings, we tend to over value recent information, so is this effect real? Check out my latest post where I use statistics to find out https://t.co/PeQ7cBC4kI.
