I had an awesome first day at @Zymergen and really looking forward to cranking out some models.

Teachers and students. UCLA is offering 3 courses in causal inference. The one in computer science is taught by Prof. Adnan Darwiche
Here is a recording of his first two lectures:

I think a lot of people underestimate the liberal arts / philosophy value of Math, CS and Stats concepts.
* Taylor Series (things don't have to be perfect to work)
* Bandits/RL (earn/learn trade-off)
* Confidence intervals (uncertainty drops with more data)

"OLS of Y on X is unbiased only if X is unrelated to the error e. If there's a term Z related to X in e, the sign of the bias is the product of the signs of Cov(X,Z) and Cov(Y, Z)"
???
"If Z hangs around X but OLS doesn't know about it, it'll give X all the credit for Z"
"oh ok"

Let's put this in its proper scale and you'll see that it's an enormous effect: 70 minutes per day = nearly 6 hours per week. A typical work week is 40 hours, so we're talking about effective savings of 15% of the work week! HUGE GAINS.

WFH saves employees about 70 minutes a day on average. Most (about 60 minutes) from no commute, and the rest (about 10 minutes) from less preparation in the morning. About 1/2 of this saved time goes to working more and 1/2 to leisure/tasks, so employers and employees benefit.

We just learned that President Bidenβs first year in office was the strongest year for economic growth since 1984.
Community note
While the economy did grow 5.7% in 2021 from the previous year, the most since 1984 on an inflation-adjusted basis, the attached chart deceptively alters the scale of the vertical axis to make the growth appear more significant.

One of the first memes I share with students. I ask "Where are you in this picture? Are you in the box of memorizing formulas or are you in the play area of math exploration?" At the end of the course, I show this meme and ask the same question.
ALT On the bottom right, there is an orange and white cat in a small cardboard box. On top of the cardboard box is a text box that says "Memorizing formulas." The majority of the image is a huge cat play area that is labeled "A universe of math exploration."

I'd take it back. There is a simpler example here: discourse.datamethods.org/t/β¦ to illustrate why the combination of experimental and observational data can inform us about individual behavior.
It shows how a simple observation can rule out the model of "no effect on any individual."

I cannot think of a simpler example than this:
