Ramesh Johari (@rameshjohari) is a professor at Stanford University focusing on the design and operation of online marketplaces. Ramesh has advised companies like @Airbnb, @Uber, @Bumble, and @Stitchfix on how to scale and improve their marketplaces. In our conversation, we discuss: → What you need to get right to build a successful online marketplace → Tips for optimizing your marketplace → An easy litmus test to see if there’s an opportunity to build a marketplace in a space → The role of data science in successful marketplaces → Ramesh’s philosophy on experimentation and AI → Implementing rating systems → Much more

@paulgp Treat it as a linear model w/ y=outcomes, X=one-way ANOVA matrix. Then apply the pairwise bootstrap (resampling (x,y) together) to get muhat, and use them to get crit values for ANOVA F-test or Turkey’s HSD. It’s robust to unequal group sizes (or more general heteroscedasticity)

@paulgp Very nice slides (not just this lecture, but the course overall)! Particular pieces of work you would highlight re: the last slide (dynamics)?

Excited to share a new blog post on large scale experimentation; how should we think about opportunity costs when there are many potential experiments to run. Also, hope you enjoy the awesome animation built by @brianedcoffey👌

The original coronavirus-testing crisis was defined by bureaucratic red tape and a blundering White House. But now a new crisis is upon us, and this time private labs are the problem, @alexismadrigal and @yayitsrob report: on.theatln.tc/ThV2nRW

Restarting our economy will require one thing above all else – testing. Testing to show who's currently infected. Testing to show who's had the virus and is immune. Social distancing won't end because it's Easter. It'll end when we have sufficient testing. Here’s how we do it.
