I've collated the publicly Brownlow model predictions + some private ones. Will do a write-up tomorrow with the results and discuss the big surprises. If you have a model, hit me up in DMs/comments! Good luck!

Feelin Fuzzy? @OSPpatrick and I work through identifying players using fuzzy joins to standardize names of sports ball players against that in your database.
We use two different techniques, using base #rstats agrep and #tidyverse -esq {fuzzyjoin}!

You can rerun my AFL Win Probability Added (WPA) analysis from my stream and thread here. If you're statistically inclined, try to build a model that's better than mine! #RStats github.com/liam-crow/AFL_WPA
Great important work being done here!
Why isn't the AFL running its own competition - why is it up to volunteers?
Had lots of fun doing this piece on the team behind @aflwfantasy - why they're dedicating hours of volunteer time to grow fan engagement in #AFLW and to improve conditions for #womeninsport more broadly. #aflwfantasy #FantasyFootball abc.net.au/news/2022-09-27/a… via @ABCaustralia

@plusSixOneblog the package got mentioned in my uni class (not formally, just when bantering with the tutor)
This is great content
Fun thing. I’m going to be doing a fortnightly piece for @abcsport this #AFLW season. Here is the first - players to watch.

AFL stats fans wanting stats reminds me of the classic image below
Also a reminder of how poor the league treats it's fans and how reliant a billion dollar industry is on volunteers

CD: We have turned this binary variable {Goal | Not-Goal} into a continuous value
Statisticians: Bravo! Less noise in this metric
CD: Now we will dichotomise the totals into this bigger binary variable {Win | Loss}
S: Wait … what?! NO!
“Expected scores” is a concept invented by Champion Data, an alternative reality in which there’s a statistical likelihood that a goal, behind or miss will be scored from a particular position. In this parallel universe, Richmond are equal with Geelong. theage.com.au/sport/afl/shou…
This is a good read forwarding to all north supporting friends
