I got laid off today, with the rest of 18F.

18F was an elite federal software shop. We made gov't websites work better, more efficiently for the American people. We saved taxpayers from getting screwed over by contractors. And were fired for it.

We made this website to tell our story:

Rdatasets is a collection of 2300 free and documented datasets in CSV format. It's a great resource for teaching and exploration!

The new `get_dataset()` function from the {marginaleffects} 📦 allows you to search and load them directly in #Rstats.

If you have an issue where Dropbox is constantly syncing while @posit.co #RStudio is open, one solution is to run the following code in Terminal:

find "Dropbox" -type d -name ".Rproj.user" -print0 | while IFS= read -r -d $'\0' folder; do xattr -w com.dropbox.ignored 1 "$folder"; done

Voters are mostly partisans who rationalize, swing voters are often ignorant and voters project their views onto their candidates. But this has always been true! The media was better once, but there was no golden age. Most of their grandparents did not read Walter Lippmann's column.

Americans are now one-third less likely to die from cancer at the same ages as Americans in 1990
How has the risk of dying from cancer changed in the United States? To understand this, we can look at national cancer death rates in the United States. The gray line shows the crude rate, which is the rate of deaths from cancer per 100,000 people. It has risen between 1950 and 1990 and has fallen slightly since then. However, cancer death rates rise sharply with age, and the age of the US population has increased since 1950, so we would expect cancer death rates to rise for that reason alone. What if we adjust for the increased age of the US population? The red line, the age-standardized rate, shows this. It shows the cancer death rate if the age structure of the US population was held constant throughout. This shows a slight rise until 1990 and then a significant decline; rates have fallen by one-third. This means Americans are now one-third less likely to die from cancer at the same ages as Americans in 1990. This comes from several factors: better screening and earlier diagnosis, medical advances in cancer treatments, and public health efforts to reduce risk factors like smoking and exposure to carcinogens.

Yes, it was an anti-incumbent environment, *globally*—but the US had weathered the pandemic economy so much better than everywhere else, it was totally reasonably to think that the incumbent party could prevail. It was not a forgone conclusion. It was close, but still decisive against incumbents.

Applied researchers often find themselves making statistical inferences in settings that would seem to require multiple comparisons adjustments. We challenge the Type I error paradigm that underlies t...
