Variable name comparison of v1 and v2 nflverse players data.

Variable name comparison of v1 and v2 nflverse players data.

Rare breaking change in the #nflverse!

`nflreadr::load_players()` now loads v2 players data.

During the process of the rewrite I decided to rename some variables for consistency and removed some irrelevant variables. Please see the below table for a detailed comparison of old and new data.

Suppose every baguette molecule is a data point, the whole loaf obviously has a negative correlation and each slice obviously has a positive correlation. Should think of simpson's paradox as a kind of selection bias. Every time you cut a data set you cut along some sort of shape.

Was taking a look at the college RTMs done by @talbtree.bsky.social

There are 3 players drafted in the top 10 of the NFL draft with a 99+ Overall Score...

Science abstract: POLICING
High-frequency location data show that race affects citations and fines for speeding
Pradhi Aggarwal1, Alec Brandon2*, Ariel Goldszmidt3, Justin Holz4, John A. List3, Ian Muir5, Gregory Sun6, Thomas Yu7
Prior research on racial profiling has found that in encounters with law enforcement, minorities are punished more severely than white civilians. Less is known about the causes of these encounters and their implications for our understanding of racial profiling. Using high-frequency location data of rideshare drivers in Florida (N = 222,838 individuals), we estimate the effect of driver race on citations and fines for speeding using 19.3 million location pings. Compared with a white driver traveling the same speed, we find that racial or ethnic minority drivers are 24 to 33% more likely to be cited for speeding and pay 23 to 34% more money in fines. We find no evidence that accident and reoffense rates explain these estimates, which suggests that an animus against minorities underlies our results.

missed this last month: data science informing psych, sociology, polisci

in Lyft data (222K drivers), Black or minority drivers get speeding tickets 1/3 more often **when they are known to be going the same speed**

beautiful work, it's racial profiling, case closed

My cricket R package (github.com/albtree/cric...) has been out of action since October after an API change. Have finally started working on it again. Popped out some Women's Premier League charts from some old code.

On discussion with my psych I set myself up a fortnightly mental health reminder of things to think about which usually help me. We identified these as themes that usually help me stay on track 😊

Trying to use mindfulness more regularly when I’m feeling overwhelmed or need a circuit breaker to help snap out of a grumpy mood. Wanted to share this one from last week, especially the quote:
“You deserve this time. You matter and so does your well being”

Good self care!
