1/ Big day for Microsoft 365 Copilot: I’m really excited about our latest update.

Copilot has truly become the UI for AI – and for me, it’s the scaffolding for my workday.

Here are four new features I’ve especially been enjoying.

[Haoran Zhao @Haoran_HZ]

Are these new func()s involved in the pystata API?

[Stata @Stata]

New in #Stata19: High-dimensional fixed effects (HDFE)

Absorb multiple categorical variables in your models with 𝗮𝗯𝘀𝗼𝗿𝗯() for 𝗮𝗿𝗲𝗴, 𝘅𝘁𝗿𝗲𝗴, and 𝗶𝘃𝗿𝗲𝗴𝗿𝗲𝘀𝘀 𝟮𝘀𝗹𝘀—without the computational burden.

Faster estimation, more focused results, better insights.

[Stata @Stata]

#Stata19 is here!

🔹 Machine learning via H2O: Ensemble decision trees
🔹 Conditional average treatment effects (CATE)
🔹 High-dimensional fixed effects (HDFE)
🔹 New and improved graphics features
🔹 And much more

It’s been 24 hours since the new EPA PM2.5 (air quality / particulate matter) standard, so that’s enough time to pass for a few hot takes. The new standard is a net positive for sure, but several important nuances to be aware of… Mega-thread! 🧵 1/

Ok this is big.

Web of Science just removed the MDPI flagship journal IJERPH from their lists. This means IJERPH has no more an Impact Factor.

Why is this big? What are the implications? 🧵

Check out our new study: influence of overhead HVAC on airborne contaminants distribution in a simulated meeting/class room #IAQ

[Berkeley Lab @BerkeleyLab]

Experimental studies of the effects of ventilation on indoor air quality found that overhead heating could result in #COVID19 hot spots. Fortunately, there’s a simple solution. @BerkeleyLabETA #IAQ

@nytimes This is such an irresponsible soft-racist headline.

Hamster ovary cell lines are how labs all over the world make proteins. I repeat: they are universally used. They were developed in a Boston lab in 1957.

Please STOP implying that the Chinese do weird things with animals

New estimates suggest the vaccine rollout is no match for the severity of the U.S. outbreak, and stricter social distancing measures will also be needed to reduce infections. https://t.co/WLmjlBB6tV
