. At first I was a bit surprised to see that every category pair showed a positive correlation, but upon further reflection it shouldn’t be that surprising: some people are just better at trivia, and they’ll tend to do well in all categories (none other than Ken Jennings himself is an active LLama!).

In order to adjust for the varying overall trivia skill, I tried adjusting all category stats by their individual user’s overall correct rate, to get the correlation between performance relative to individual averages for each user/category.

For example, my overall correct rate is 48.7%. Since I’ve answered 81.8% of my math questions correctly, that gives me a (81.8 – 48.7) = +33.1% relative outperformance in math. I’ve answered 28.6% of my theatre questions correctly, so for theater I have a (28.6 – 48.7) = -20.1% relative underperformance to my average.

When we do the same correlation calculation between category pairs, this time using each category’s user-specific relative performance, we see some negative correlations. For example, people who have television as one of their top categories are most likely to have world history as one of their worst categories. Again the full list of these relative correlations is available in the spreadsheet, in the second tab

Single-occupancy restrooms are simply an impractical and unworkable setup for most offices. Larger companies would need a whole floor or two to accommodate enough of them.

OSHA rules require that workplace bathrooms remain clean and dry and a mop can slide right under partitions. In addition, the economics of an enclosed latrine don't make sense.

Tuesday, Instagram said it overhauled its “Explore” tab to allow users to see images taken at a specific place or under the most popular hashtags. It also introduced a more powerful search function that lets users search for images by people, hashtag and place.

The changes will help users track live events, ranging from last month’s flash floods in Houston to Taylor Swift’s concert tour, Systrom said. Now Instagram Wants to Be Source for Real-Time News - Digits - WSJ

We saw earlier that recently originated loans have defaulted at a much lower rate than loans originated during the bubble years. For one thing, home prices bottomed out sometime around 2012 and have rebounded some since then. The partial home price recovery causes current LTVs to decline, which as we’ve seen already, should correlate to lower default rates.

This example is influenced by a New York Times op-ed by John Geanakoplos and Susan Koniak from March 4, 2009.

I used to work with Professor Geanakoplos, and I helped him compile the data for the article. I remember getting kind of annoyed when the NYT’s graphics department decided to rotate our graph by 90 degrees and add a cheesy water effect to evoke “underwater” homeowners – it turns out the graph was done by Nicholas Felton, a highly regarded graphic designer! I still think it was a mistake to rotate the graph like that, since it made it harder to interpret the actual data, but c'est la vie
