My name is Hal Svien; this is my data science blog where I’ll explore some data sets and answer questions that I find interesting. See the About section for more about me and my background, education, and my approach to this blog. I’ll include my citations with every post, and you’ll notice some come up frequently. I’ll end up using books by Scott Baldwin, Rex Kline, Neil Salkind, and Rebecca Warner because they are very elaborative, often giving examples from simulation data or the like to show you why what they’re discussing is accurate. /contact/ Mon, 01 Jan 0001 00:00:00 +0000 /contact/ You can contact me a few different ways: halsvien@gmail.com, through LinkedIn or GitHub (linked at the top of this page) or really any other way you can find me. /crime-data/ Mon, 01 Jan 0001 00:00:00 +0000 /crime-data/ UCR Data 2000-2019 This is my page for crime data sets I’ve created for anyone to use!
