Think of it as a pre-flight checklist for your data. Skip it, and you risk landing in entirely the wrong place. Why Diagnostics Matter Most statistical methods rest on assumptions — about how data are distributed, how variables relate to one another, and how errors behave. When those assumptions break down silently, the model keeps running and happily produces numbers that mean very little.https://mscazmy.github.io/2024/02/10/public-health-ethics/Sat, 10 Feb 2024 00:00:00 +0000https://mscazmy.github.io/2024/02/10/public-health-ethics/What is Ethics?

The general idea was to share with the world that, although we create complex and polished stories for the internet, we routinely cull ideas or drastically change them before they make it to the public eye. I wanted to help normalize that it’s ok if your original idea for a data or research project doesn’t work out.https://mscazmy.github.io/2019/06/02/failure/Sun, 02 Jun 2019 00:00:00 +0000https://mscazmy.github.io/2019/06/02/failure/Me and Failure Go Wayyy Back For as long as I can remember, I’ve had a hard time with failure. My intense aversion to it was immortalized on my bedroom wall for most of my childhood in the form of an imperfect piece of artwork. I had been coloring in a ballerina Barbie from some coloring book or another when my hand slipped, a single crayon line extending outside the boundaries of Barbie’s body and into the clean expanse of the rest of the page.https://mscazmy.github.io/2018/07/06/flexbox/Fri, 06 Jul 2018 00:00:00 +0000https://mscazmy.github.io/2018/07/06/flexbox/This post is available in its entirety on The Pudding.

I had been building a stacked bar chart in D3.js, and was seriously struggling to get the bars to stack on top of each other nicely and to animate from the bottom of the graphic instead of the top.https://mscazmy.github.io/2018/03/26/purrr/Mon, 26 Mar 2018 00:00:00 +0000https://mscazmy.github.io/2018/03/26/purrr/Why purrr? Ah, the purrr package for R. Months after it had been released, I was still simply amused by all of the cat-related puns that this new package invoked, but I had no idea what it did. What did it mean to make your functions “purr”? I started seeing post after post about why Hadley Wickham’s newest R package was a game-changer. But it was actually this Stack Overflow response that finally convinced me.https://mscazmy.github.io/2017/11/15/syntaxhighlighting/Wed, 15 Nov 2017 00:00:00 +0000https://mscazmy.github.io/2017/11/15/syntaxhighlighting/The Backstory I’ve been playing with Yihui Xie’s blogdown package for almost a year now, and I’m constantly amazed by all of the things that it can do. Maybe I’ll get around to turning this post into a series, with each addition explaining one more cool thing that you can now add to your blog posts from R. But, for now, there’s just one I’d like to touch on: syntax highlighting.https://mscazmy.github.io/2017/05/02/nesting/Tue, 02 May 2017 00:00:00 +0000https://mscazmy.github.io/2017/05/02/nesting/Introduction Before Nesting Nest Level 1 Rollup Level 1 Sorting Keys Nest Level 2 Styling Nested Elements Creating Dropdown Menus from 1st Level Nests Rollup Level 2 Creating Dropdown Menus from 2nd Level Nests Introduction While learning how to make interactive data visualizations using d3.js, I ran into an issue with something new to me: nests. The general idea is that data sometimes needs to be grouped based on certain variables and the groups need to be analyzed or graphed separately.https://mscazmy.github.io/2016/12/19/website/Mon, 19 Dec 2016 00:00:00 +0000https://mscazmy.github.io/2016/12/19/website/Since the writing of this post, simpler methods of setting up sites have been documented.
