It is soft-launched, but my python package `crimepy` is intended to contain most of the work in my career. github.com/apwheele/cri...

Book review on the Idea Factory: Bell Labs and the Great Age of American Innovation. Had no idea Bell had its hand in so many of the building blocks of modern computing. It is also interesting how science + engineering can come together to build great things. andrewpwheeler.com/2025/09/02/r...

I have updated my Sworn Dashboard, according to the FBI, the percent of female sworn has gone down in 2024 after consistent rises over the last 8 years. This is mostly due to composition though, more agencies are reporting in the FBI database than in prior years.

Deep Research tools cite open access work much more often in my experiments than closed source materials. I go over a few examples for Google, ChatGPT, and Perplexity in this blog post. andrewpwheeler.com/2025/08/28/d... CJ folks should be posting pre/post prints to plain text HTML (like CrimRXiv)

The local newspaper did a writeup of this in Raleigh -- Cisco does a round of layoffs every year (I guess for quarterly reporting to make expenses look lower). There are people who go on the merry go round and like it (they get several months of severance and then get hired back). Free vacation.

Pro python tip, I like to develop in the REPL. That way I can use the reload library to edit functions. E.g. from src import myfunc test = myfunc(...) # errors out Then can do from importlib import reload reload(myfunc) # edit the source before this test = myfunc(...) # works

New blog post, using the SPPT to monitor changes in crime patterns. crimede-coder.com/blogposts/20... Many of the other techniques (ESRI's emerging hotspots, or KDE maps) tend to be too noisy. This controls for multiple comparisons.

Recently found James Tuttle's substack on macro crime trends in the US. It is an excellent follow crimeforecast.substack.com/p/the-smartp...

Using Chicago open data for some example graphs, here is the time series trends for street robberies. Basically as low as it has been going back to 2015

My peer reviewed paper on up-adjusted NIBRS crime estimates based on domestic violence victimization reporting rates (with Alex Piquero) is now out in Crime & Delinquency. journals.sagepub.com/doi/10.1177/...

Reminded of this old blog post in a thread on X, if you want to know how to fit a plateau in a regression model, this shows one way to constrain the coefficients and fit the model in scipy. andrewpwheeler.com/2022/05/02/f...

Reminded of this old post, as Chris Bruce is doing a talk on historical overview of the crime analysis field. Seattle hotspots are basically unchanged in 100 years (Schmid has a few in the 20's). andrewpwheeler.com/2015/06/12/f...

New blog post, in which I discuss the error of "the difference between stat significant and not is not itself stat significant". It often causes people to post-hoc try to explain things that are easily just due to the standard error of estimates, andrewpwheeler.com/2025/07/28/t...

For an example much simpler than a pelican riding a bicycle, both Claude and ChatGPT cannot create an SVG knife.

Is gun shot detection tech worth the cost? I give an example cost-benefit analysis in this blog post, discussing lives saved. There is no consistent evidence at this point GSD reduces crime or increases clearances. crimede-coder.com/blogposts/20...

New blog post on project management, andrewpwheeler.com/2025/07/20/s... High level goal make a list of things to-do and do them in a reasonable amount of time. Everything you do should keep these high level goals in mind.

Another example of a prof selling their own self published (likely mediocre) book to thousands of students. The article does not say online, but this prof may have made over 100k profit per year from sales. dailyemerald.com/152165/featu...

New blog post, I show how to use LLMs to extract pieces of information from plain text, with an example of extracting out info like modus operandi from police narratives crimede-coder.com/blogposts/20...

Purchases for the Data Science for Crime Analysis with Python continue to trickle in, crimede-coder.com/blogposts/20..., One of the reasons I promote python is because python jobs are much more common in private sector. It is IMO a better personal investment than R.

Weekend project, using R2 + DuckDB wasm to build a low price frontend for big data analytics crimede-coder.com/graphs/GSUBo...

New blog post, finding outliers in proportions crimede-coder.com/blogposts/20... Useful for flagging officers in early intervention systems, or examining data with varying denominators.

New blog post, academic criminologists should be more focused on building stuff than writing papers, andrewpwheeler.com/2025/06/12/b...

With the new ASEBP site, my Criminal Justician essays were not transferred over. Putting them up on my crime de-coder site. First one is description why I am skeptical of a study of Denver alt response having large crime reductions, crimede-coder.com/blogposts/20....

I recently received a question on Poisson vs OLS models for a dose response relationship, and posted the exchange to my blog. Long story short even with count data OLS models can make sense, it depends on the functional form. andrewpwheeler.com/2025/05/28/a...

Besides the fact you could almost do this yourself anymore (you can post pre-prints with self-cites and they get picked up). My personal blog is picked up by Google Scholar. Blog cited around ~10 times in real papers, and it had references in the posts. Then GS crawled rest of my site.

Paper with Scott Jacques on stripping sensitive information from narratives is out, www.qualitativecriminology.com/pub/zhiuy6jg.... Ultimate goal to make it easier for qual people to share there data for replication. Has links to python code and uses open source models.

Please make your papers open access: there really are people out there who want to read them but don’t have access to subscription journals. Fortunately, making your work open access is both very easy and 100% free: www.lesscrime.info/post/how-to-...

Most of my personal work on creating reports I have migrated from Jupyter notebooks to Quarto. Here is a video tutorial I made for Kansas City crime analysts python training using Quarto + VS Code. www.youtube.com/watch?v=gaPP...

Are you interested in designing network experiments where you control the number of direct treated vs spillover? Check out these functions I have written in python to optimally spread out treatment in your network given constraints github.com/apwheele/Blo...

Eric Piza has a nice set of courses on crime mapping using ArcGIS in his grad program at Northeastern www.crimrxiv.com/northeastern...

I put my notes on using python + ArcGIS (mostly have been posting on LinkedIn) on my blog. Mostly for the bots at this point to read and have better examples. andrewpwheeler.com/2025/04/20/u...

New blog post on how to format different queries to grab open data on ESRI servers, which many cities have, andrewpwheeler.com/2025/04/14/s...

New blogpost on Crime De-Coder collating extensions to the WDD stat I made with Jerry (different pre/post time periods, normalizing per area, combining harm weights, and continuous monitoring) crimede-coder.com/blogposts/20...

After a long, long wait (and a transition from academia to private sector), our paper is finally out! www.sciencedirect.com/science/arti... We used a unique source of data tracking residents of Milwaukee from the 1980s through the 2020s to examine the role of alcohol abuse on gun violence.

Trying out Google's Deep Research, I asked about developing a protocol to measure mental health and stress in police officers. Here is the report, docs.google.com/document/d/1...

I am doing a webinar with VCAN this Friday, Simple Stats for Evaluating Crime Reductions, virginiacrimeanalysisnetwork.org/event/simple... This is work I did with Jerry Ratcliffe on using the Poisson distribution to est. crime reductions based on simple counts pre/post in treated and control areas.

On a more serious note, I have a weekly newsletter that you might enjoy if you're new. Sign up at Jasher.substack.com

Many first and second degree connections in my network are being laid off. Either due to the directly federal gov cuts, or due to cuts to federally grant funding. I have put to paper various resources for students applying to tech jobs, but they are just as useful in your situation.

New blog post, crime analysts should learn SQL as it is faster, more reliable, and is a more transferable skill to other analyst roles crimede-coder.com/blogposts/20...

gmcirco.github.io/blog/posts/f... Gio examines the time in between traffic tickets to show implausible distributions in the recorded CT stop data. I.e. officers saying they did multiple stops within 10 minutes.

The article on our NIJ competition winning recidivism model (joint work with Gio Circo) is out (academic publishing is crazy slow, the competition was 4 years ago). journals.sagepub.com/doi/10.1177/... Anymore, picking up some machine learning for analysts is not crazy.
