Top posts from The DO Loop in 2020


Last year, I wrote more than 100 posts for The DO Loop blog. In previous years, the most popular articles were about SAS programming tips, statistical analysis, and data visualization. But not in 2020. In 2020, when the world was ravaged by the coronavirus pandemic, the most-read articles were related to analyzing and visualizing the tragic loss and suffering of the pandemic. Here are some of the most popular articles from 2020 in several categories.

The coronavirus pandemic

Relationship between new cases and cumulative cases in COVID-19 infections

Statistical analysis: Regression

Visualization of collinearity diagnostics

Other statistical analyses

Data visualization

Many articles in the previous sections included data visualization, but two popular articles are specifically about data visualization:

Reference lines at values of statistical estimates

Many people claim they want to forget 2020, but these articles provide a few tips and techniques that you might want to remember. So, read (or re-read!) these popular articles from 2020. And if you made a resolution to learn something new this year, consider subscribing to The DO Loop so you don't miss a single article!

  1. 2020 certainly was a year where analytical and visualization skills were of value. I love that you keep your readers informed of statistical techniques in an learned way that is also relevant and helpful. I look forward to another year of being a DO Loop avid reader and fan!
