APBRmetrics

Just wanna thank everyone for helping out, I was able to get it to work. Just getting through picking the best Lambdas now, but I really apprecaite the advice everyone gave me here it helped me out a ton

Also - of course, use sparse matrizes - Mac's are better at memory handling with sparse matrizes than Windows/Unix, in case you have a choice - given it's the number of columns that's creating problems, you could - like in the early APM days - handle all players below a certain minute threshold as ...

I personally have not experimented with luck adjustments. If I were to include them I would definitely include free throws but not sure about 3 pointers. Some teams like Houston for example do seem to have a measurable effect in reducing 3 point percentage. Also JE has said that it doesn't lead to ...

The prior is usually box stats regressed against RAPM. The way that I've seen prior informed RAPM calculated here, as well as other places, is to create an expected score margin from the linear combination of player priors on the floor. You then subtract the expectation from the actual results and ...

Hi! I was interesting in playing around with RAPM and creating one of those fancy all in ones with it, but I was just wondering a few questions when it came to RAPM. I have a play by play data set, and right now have it set when it comes to possessions as - Getting an offensive rebound off a missed ...

So its working but its incredibly slow (going to take around 2-3 days to get the data I need), or is that just how long it would be expected to take? it gets box score id, and then play by play id since it cant get play by play id directly.

This will be sort of a solution. There is an R package that scrapes pbp from stats.ncaa called bigballR. There is a function called get_play_by_play which scrapes the pbp and a function called get_possessions which parses it and returns information that includes the players on the court. The proble...

Does what bigdataball have what you want? Have you checked with herhoopstats.com? Can you scrape from ncaaw official site or possibly request a download? Are you doing basic research to share with public or for a commercial purpose? BigDataBall doesn't have NCAA Womens data, but it essentially has ...

Hello, I want to try to parse Play by Play data for College womens basketball, similar to https://www.bigdataball.com/datasets/wnba/historical/ As of right now, the only code I found on github had everything except for the players on the court, which is a bit important as I want to run RAPM using it...

As part of my work on revising Box Plus/Minus, I am investigating using a two-dimensional position spectrum rather than the conventional positions. I started down this road with BPM 2.0 and I am moving further that direction with the next revision of BPM. The two dimensions I am proposing are gener...
