Pretty charts aside, the point is I don't even need other features to create an awesome readmissions model. In fact, when I add in my 800ish column modeling asset (on which I should write a blog) the auc creeps up to 0.80, which is definitely worth…

David Napoli This is great work incorporating social determinants of health data into predictive modeling — I would love to see what data elements such as Social Vulnerability Index would add to such efforts

If you're like most people who have attended one of my webinars or spent time checking out my resources, at some point you might wonder: Because you're seeing my presentations after about 15 years of trying to make them effective and engaging, it…

David Napoli A strong purpose and passion (for the topic *and* your audience) … great post on what is needed for a great presentation

We recently went through a common process at Mode; we considered bringing on a new tool for our data infrastructure. While those of us on the analytics team have a deep understanding of our data stack, we're not experts in security. Before we bring…

David Napoli Or why the role of the analytics workflow — and especially the analyst(s) involved — is to provide information understanding to their stakeholders which elicit engagement and enlightenment that result in wisdom and action

There is a popular adage about academic writing: “Writing is thinking.” The idea is this: There is a simple view of writing as just an expressive process – the ideas already exist in your mind and you are just putting them on a…

David Napoli Excellent read on the data analytics process, what can arise that leads to items such as p-hacking, and what should be done to avoid such ethical errors

Back-to-basics with nuanced vocabulary I'm about to prove to you that statistics are boring... to help you appreciate the point of all those fancy calculations that statisticians like myself get up to. As an added bonus, this is pretty much what…

David Napoli A good post exploring the usefulness underlying several statistics terms … not so boring after all!

For too long, many scientists' careers have been built around the pursuit of a single statistic: p<.05. In many scientific disciplines, that's the threshold beyond which study results can be declared “statistically significant,”…

David Napoli If all the talk and articles on p-values and p-hacking have you (a bit) confused, this post will help clear things up

How to Animate a Tableau Viz in 4 Steps This is a step-by-step guide on how the Tableau JS API can be used to animate Tableau Public dashboards embedded in Observable notebooks. Here I have recreated the Wealth and Health of Nations chart that was…

David Napoli Another great way to animate your Tableau data visualization … this one remakes the great Hans Rosling's Gapminder visualization

Multivariate Reporting (also known as Small Multiples) uses a series of visuals with the same measure and same scales but showcases various partitions of the data. The benefit is that you can allow your report consumers to easily compare the same…

David Napoli This … um … it should not be this 'involved' to create small multiples in a visualization tool. IMHO, this is a 'fail' in that Power BI has to jump through hoops or rely on custom visualizations to create small multiples. It should be a standard feature.

Five years ago I read Daniel Markovitz's argument for migrating to-do lists into calendars. Since then, my productivity has at least doubled. That momentous (at least for me) article describes five problems with the to-do list. First, they…
