CPAs are rates not costs (despite the name). Perhaps this is the most obvious thing ever, but a quick blog about this here! (Don't look too closely at the blog, i just set it up👀) chelseaparlett.github.io/posts/2026-0...

Well I’m gonna read for fun even HARDER now😤

Buy books (not from Bezos) 🥳📚

TFW fucking binary search actually came in handy today

Will this little treat *actually* make my life better or am I just having a stressful day at work 🤔

The great @tylerjamesburch.com is speaking at our virtual SoCal R User Group meeting this Thursday at 6:30pm (pacific) 🤩⚾️ And you should join! ⬇️ www.meetup.com/socal-rug/ev...

ATTENTION EVERYONE! I sewed Nova a bucket hat🥹🧵🪡

If i were on Love Island, i would take the opportunity to upskill every islander’s data literacy. There’s so much down time in the villa, everyone is leaving with the ability to assess causal claims and understand uncertainty in estimates🥰

"don't do that" as a service

90% of my stats advice in a nutshell: - don’t do it - use a simpler model - stratify - it’s about 10%

In the interest of inclusivity☺️ I’m amending my language: There are no ethical (b|tr)illionaires 🫶

AI is a tool that *can* create value when used correctly for the right problem, it is NOT a value in and of itself.

Had a wonderful time at ❄️ Snowflake Conference this week but more IMPORTANTLY, got to add another California library card to my collection😎📚 AND got to take public transportation to get it 🚊 Favorite thing to do when traveling in California (as a resident).

Why do AI apps always lean towards logos that look like vague representations of anuses? 🍑

Y’all don’t think about experimentation enough

Psychologists doing clustering be like: #statsmeme

I’m not a violent person, but sometimes…people annoy me ✨just enough✨ for me to tell Nova (my corgi) that should she ever be in the presence of their exposed ankles, she should feel free to nip at them😇🙂‍↕️

Cauchy? The nicest distribution ever. It doesn't have a mean bone in its body.

You make fun of horoscope girlies ⭐️ but then you let a pile of linear algebra tell you what to do….

No matter how it improves in the future , I will never feel the same level of fondness for matplotlib as I feel, deep in my bones, for ggplot😍🥰

May is shaping up to be a great reading month 📖

Do I not have the cilantro soap gene OR do I just think that sometimes soap is a nice flavor to include 🤷‍♀️

The only way to understand statistics is through linear algebra.

Flights of less than 350 miles should be a train ride. 🙃

The new Dungeon Crawler Carl comes out in 2 days

inside me are two wolves: - the wolf that thinks we need to show students challenges with NHST inference in huge (millions+) datasets and

You can’t just “do AI” if you don’t have good data and good documentation.

My grandpa: “I have found that the only way to goad busy numerical analysts into action is to claim that a subroutine is infallible” 😂 I guess the whole “the quickest way to get an answer is to post an incorrect on on the internet” was true even pre-internet 💀

Me: complaining that Canva docs don’t support in-line LaTeX @tonypelleriti.bsky.social: maybe they have a latex allergy

the only good thing* about having to use the delta method is getting to make @drob.bsky.social’s “(Taylor’s Version)” joke when writing it up *besides the fact that it “gets me” the “answer that I need”🙄

🤯 just had a wild experience. I needed to choose a hyperparameter value, 10 had good vibes so I used 10 for now. Later wrote a simulation that showed 10 is exactly when diminishing returns kick in (> 10 gives no benefit, < 10 shows poor performance). I think my brain subconsciously knew this 👻👻

WHY DONT WE HAVE RANKED CHOICE VOTING in CA Gubernatorial primaries?! (Or something even better, I’m not super educated on all the choices)

I am SO DELIGHTED that public libraries exist🥹 I went to return a book (operation bounce house) and pick up a new one (bobiverse #2: for we are many) and I was so HAPPY to see so many people there enjoying books, services, or just somewhere quiet to exist without buying anything 🙏 Truly incredible.

Me when I’m hoisted: surely this isn’t my own petard…🤨

I miss the “less is more” energy that generative AI work had in 2023/2024🥹 (quantization, specialized models, heuristic models with AI supplementing where it was actually useful) This is just a personal VIBE I’m getting, but now that genAI is more widespread it feels like (1/2)

data that’s clean, hallelujah. MCAR, hallelujah. bayesian priors, hallelujah. stakeholders on board, hallelujah. narrow CIs, hallelujah. ROI > 1, hallelujah.

Have you ever thought “this horror book doesn’t have enough statistics in it?” 🤔 Then have i got a book for you! Statistical, absurdist, horrific, and a little gay😚👌 this was a fun read. www.goodreads.com/en/book/show...

Ooop someone just accidentally reinvented meta-analysis again🤭

Nothing is certain except: - death - taxes - posterior intervals with overly narrow priors

One thing that’s stopped me from dreaming about being a Data Science Influencer™️ is that it seems like there’s so much pressure to put out such a VOLUME of content that you can’t make it all thoughtful/correct🤔 It’s just so effortful to put out content that’s helpful, original, + well thought out

the fact that @overleaf.com doesn't know Frequentist is a word is...interesting👀

Kinda peeved that out of all the cool work I did today the most impactful piece was a descriptive boxplot

Me when I’m writing for a respectable, very professional company so I can put my shitty jokes in 😒

YOURE NOT GOING TO BELIEVE THIS. I set out a mug + tea bag of what I THOUGHT was lemon balm, and @tonypelleriti.bsky.social boiled water and made me the tea. TURNS OUT I HAD ACCIDENTALLY GRABBED black tea. Instead of a calming bedtime libation, I drank 50mg of caffeine @ 11pm 🫠

Me drinking my bedtime Lemon Balm Tea in case it will magically cure all my stress and anxiety 🙂🍵

This is another great example of a rule that resonates with me: When someone asks you to send more time consuming/interacting with material than was spent creating it, it is 🫩SOUL CRUSHING🫩

I used to think it was so quaint in recency novels when ladies would “catch up on their correspondence” So tell me why I just spent 30 minutes responding to various unread messages that have accumulated the last few days😂

I feel bad for medical doctors. I would hate watching so many popular shows about statistics and seeing them get everything wrong 😵‍💫
