Experiment without the wait: Speeding up the iteration cycle with Offline Replay Experimentation. Awesome work by my colleague Maxine @PinterestEng link.medium.com/NoktNr7cXmb

@sastoudt @BucknellU Congrats Sara!!! They are lucky to have you :)

Grades are in + I'm two weeks post second vaccine dose, so it feels like a good time to announce where I'm headed next. I'm excited to be joining the @BucknellU Mathematics Department as a tenure-track Assistant Professor in the fall. 🥳 Working with data in PA? Let me know!

@PandaGlazer Congrats!!

Update: I kicked 🍑!!

@TinaLBarton We've moved to a directly responsible individual (DRI) system to simplify things. Every project has a DRI who makes the final call. If it's cross-functional, there can be a DRI from each team. Pros: speed and clear ownership. Cons: up to the DRI to loop in others.

Looking for input... Do you use the RACI matrix for your team? If so, what are the pros and cons? If not, what do you use? #teamworksolutions

Despite being on Twitter right now, I think social media is wrecking our brains. Especially bad during COVID, with fewer options to go out and do things. Sharing my thoughts on how I'm trying to better utilize my free time. kellieotto.github.io/posts/2021/04/…

I've been using this internal tool at Pinterest for years and it's indispensable to my work. Congrats to the team launching this! Open sourcing Querybook, Pinterest’s collaborative big data hub by @PinterestEng link.medium.com/1MbAGjuu3eb

First blog post in ~2 years, about what's been top of mind for me lately: ways I'm practicing essentialism while working in tech kellieotto.github.io/posts/2021/02/…

@sastoudt @CieraReports @valeri_vasquez @codeforsociety @AcademicDataSci This is SO COOL 👏

Work w/ data & want to reach beyond the few people who "get" what you do? Be heard by more when you make your work more accessible. Get creative w/ a new project @CieraReports, @valeri_vasquez, & I are excited about: @datasciencebydesign/data-science-by-design-4895df6d0634" target="_blank" rel="nofollow noopener">medium.com/@datascienceby… Thanks @codeforsociety @AcademicDataSci

Wow. Two Rep. members of Board of Canvassers refused to certify election in Wayne County, MI if votes from Detroit were included. Trump tweeted his support of this. Board has since voted to certify, but fellow board member @NedStaebler has some strong words for his colleagues

Is Trump right about Georgia vote? news.berkeley.edu/2020/11/13/is-… via @ucberkeley @philipbstark

@2plus2make5 Have to coordinate sampling across counties. Need a sampling frame in the form of "ballot manifest," a list of ballot IDs and storage locations. Different pools of ballots (mail, in person, provisional). Wrote a paper on these issues (audits, not polling) arxiv.org/abs/1812.06361

Why don't states just take a random sample of 10,000 of their ballots and count them very quickly at the start? That would enable you to quickly determine who's probably going to win. I assume there's a good reason they don't do this, but can someone explain to me what it is?

@willafriedman This paper I worked on during grad school uses two unique sets of student evaluations of teaching to show evidence of gender bias in these evals. scienceopen.com/hosted-documen…

Examples of papers using two different datasets/methods to answer the same question?

Election commission orders top voting machine vendor to correct misleading claims. "DS200 optical scan machines *with modems* are in use in 11 states and the District of Columbia" -- scary. politi.co/323C5Gb.

@sastoudt "Best" procedure: use a long (10-20 digits) random number from another source as the seed. Bad procedure: seed with a lot of zeros. See section 4 (this came out AFTER my dissertation of course) arxiv.org/pdf/1910.06437…

How do you pick a seed for your RNG? I'm trying to explain my own weird system on some R labs based on all of the drama in "sample" and a vague memory I have of @kellieotto telling me to avoid zeros in a seed(?) and I could use some backup.

I, like she, got into a lucky situation with a great advisor who supported me and taught me a lot. I got to work on projects I cared about and touch many topics. Not everyone has that experience.

It's time for statistics departments to start supporting their applied students. @rlbarter shares what I've been thinking for years. It's BEEN time for the field to change, or lose a lot of great people. rebeccabarter.com/blog/2020-07-3…

I made it to the big time!

How you’re using Pinterest gives us hope. #StayINspired.
