For some housekeeping, if you are not signed up, also make sure to sign up for the RSS feed of my crime de-coder blog. I have not been cross posting here consistently. For the last few posts: Using…| Andrew Wheeler
Easily one of the most common critiques I make when reviewing peer reviewed papers is the concept, the difference between statistically significant and not statistically significant is not itself s…| Andrew Wheeler
Have recently participated in several projects that I think went well at the day gig – these were big projects, multiple parties, and we came together and got to deployment on a shortened timeline.…| Andrew Wheeler
The motivation here, prompted by a recent question Abigail Haddad had on LinkedIn: For the machines, the context is hosting a dataset of 150 million rows (in another post Abigail stated it was around 72 gigs). And you want the public to be able to make ad-hoc queries on that data. Examples where you may […]| Andrew Wheeler
Jon Brauer and Jake Day recently wrote a response to my build stuff post, Should more criminologists build stuff on their Reluctant Criminologists blog. Go ahead and follow Jon’s and Jake’s thoughtful work. They asked for comment before posting – I mainly wanted to post my response to be more specific about “how much” I […]| Andrew Wheeler
I have had this thought in my head for a while – criminology research to me is almost all boring. Most of the recent advancement in academia is focused on making science more rigorous – more open methods, more experiments, stronger quasi-experimental designs. These are all good things, but to me still do not fundamentally […]| Andrew Wheeler
Crazy busy with Crime De-Coder and day job, so this blog has gone by the wayside for a bit. I am doing more python training for crime analysts, most recently in Austin. If you want to get a flavor of the training, I have posted a few example videos on YouTube. Here is an example […]| Andrew Wheeler
I shared a series of posts this week using Esri + arcpy tools on my Crime De-Coder LinkedIn page. LinkedIn eventually removes the posts though, so I am putting those same tips here on the blog. Esri’s tools do not have great coverage online, so blogging is a way to get more coverage in those […]| Andrew Wheeler
The end goals I want for a social media site are: promote my work see other peoples work Social media for other people may have other uses. I do comment and have minor interactions on the social media sites, but I do not use them primarily for that. So my context is more business oriented […]| Andrew Wheeler
Line plots are probably the most common type of plot I make. Here are my notes on making nice line plots in matplotlib in python. You can see the full replication code on Github here. First, I will…| Andrew Wheeler
So you probably learned about confidence intervals around means in your introductory statistics class. For a refresher, a confidence interval covers a particular statistic at a pre-specified rate. …| Andrew Wheeler
Recently ProPublica published a map of uses-of-force across different jurisdictions in New Jersey. Such information can be used to monitor whether agencies are overall doing a good or bad job. I…| Andrew Wheeler
For a recent project of mine I was exploring arrest rates at small units of analysis (street midpoints and intersections) for one of the collaborations we have at the Finn Institute. One of the gra…| Andrew Wheeler
Just a few years ago, most cities open data sites were dominated by Socrata services. More recently though cities have turned to ArcGIS servers to disseminate not only GIS data, but also just plain…| Andrew Wheeler
One area of prediction in criminal justice I think has alot of promise is using predictive algorithms in place of bail decisions. So using a predictive instrument to determine whether someone is de…| Andrew Wheeler
I recently read JD Vance’s Hillbilly Elegy. I grew up in very rural Pennsylvania in the Appalachian mountains, and I am the same age as Vance. So I was interested in hearing his story. My backgroun…| Andrew Wheeler
Two resources I have been consuming lately I would highly recommend: How to measure anything by Douglas Hubbard Keith McCormick’s short LinkedIn courses, particularly just went through estimating r…| Andrew Wheeler
The recent work on investigations in the criminal justice field has my head turning about potential quantitative applications in this area (check out the John Eck & Kim Rossmo podcasts on Jerry…| Andrew Wheeler
Motivated by a recent piece by Wood and Papachristos (2019), (WP from here on) which finds if you treat an individual at high risk for gun shot victimization, they have positive spillover effects o…| Andrew Wheeler
Recently for a crimede-coder project I have been building out a custom library to make nice leaflet maps using the python folium library. See the example I have posted on my website. Below is a scr…| Andrew Wheeler
I’ve previously written code to conduct Aoristic analysis in SPSS. Since this reaches about an N of three crime analysts (if that even), I created an Excel spreadsheet to do the calculations …| Andrew Wheeler
One of the ideas that has come up with the recent GenAI craze is to use these tools to conduct end-to-end data analysis. So you feed it a dataset + a question and out pops an analysis. Mike Zidar h…| Andrew Wheeler
So my book, Data Science for Crime Analysis with Python, is finally out for purchase on my Crime De-Coder website. Folks anywhere in the world can purchase a paperback or epub copy of the book. You…| Andrew Wheeler
I have posted on Github my notes on creating a word template to use with quarto. And since Quarto is just feeding into pandoc, those who are just using pandoc (so not doing intermediate computation…| Andrew Wheeler
After publishing my post yesterday, in which I said you could not estimate the false positive rate using conformal sets, I realized there was a way given the nature of if you know some parts of the…| Andrew Wheeler
I had a friend the other day interested in a hypothesis along the lines of “I think the mix of crime at a location is different”, in particular they think it will be pushed to more lower level prop…| Andrew Wheeler
