@juliesquid @gavin_fay @hadleywickham Missed chatting with you too. It’s been so hard not being there this year.

I missed hanging out with @CVWickham who I love chatting with and scheming about nerdy acronyms and marine puns with @gavin_fay too. And congratulations - @hadleywickham is a very happy and proud uncle 💕

What an amazing few days. I have so many wonderful messages I can't wait to catch up on and moments to share. Here is a start: today I'm w @eeholm at @NOAA HQ and we've been co-working in @quarto_pub 🌈

@gdequeiroz @astroeringrand @kara_woo @beeonaposy @ludmila_janda Me too!

@astroeringrand @kara_woo @CVWickham @beeonaposy @ludmila_janda no way! Can't wait for next year and see all these little nuggets

@kara_woo August 2021 for us…I’m using baby loosely since he’s acting a lot like a toddler 😬

Starting soon...my talk at @RLadiesDC #1" target="_blank" rel="nofollow noopener">cwickham.github.io/this-month-I-l…

@healthandstats Feeling the same. I now realise I should have blocked out the entire day in my calendar, like I would have if I had to travel to be there.

It was great to share progress on our open source textbook, Research Software Engineering with Python, at #ARDCSkills2020 today. Feedback welcome! #SoftwareSkills #TrainingResources @k8hert @lwjohnst @joelostblom @CVWickham @gvwilson merely-useful.github.io/py-rse/

@strengejacke @JennyBryan Maybe I call this the unwrapping packages from Amazon metaphor

@CVWickham I also like that one, although less "metaphoric". I can't remember exactly, but I think its from a presentation/blog-post by @JennyBryan or @CVWickham...

Do you have a favourite metaphor for subsetting lists in #rstats? I'm collecting links for my students. So far, I've got the condiments metaphor (#lists-of-condiments" target="_blank" rel="nofollow noopener">r4ds.had.co.nz/vectors.html#l…) and the train metaphor (#subset-single" target="_blank" rel="nofollow noopener">adv-r.hadley.nz/subsetting.htm…).

Doing your part to stay away from everyone? Treat yourself by watching @CVWickham first @pluralsight course "Building Your First R Analytics Solution" bit.ly/2QKXpeG. Happy to set up anyone with a 30-day free trial. #rstats

@IsabellaGhement My interpretation (of my own notes 🤔) is either approach is should get you to the same place.

I am not sure how to interpret this: "Fit regression model, use differenced series, or specify ARIMA(0, d, 0) errors." Fit regression model to differenced series x_t and y_t assuming ARIMA(0,0,0) errors? Fit regression model to original x_t and y_t assuming ARIMA(0, d, 0) errors?

@CVWickham: Charlotte, I am reading your excellent slides on spurious regression (stat565.cwick.co.nz/lectures/12-sp…) and am not sure I am interpreting your "Strategy for Regression" correctly.

@IsabellaGhement I'm hesitant provide a concrete answer to this, since my head has been out of this material for too long. My intuition says yes, but I'd check by simulating and testing it out.

If y_t and x_t are non-stationary (e.g., both exhibit a linear trend), can we fit a model of the form y_t = beta0 + beta1*xt + e_t to the original time series which allows e_t to be ARIMA(0,d,0) and examine the residuals r_t of this model for ARMA(p,q) structure?

@pachamaltese @hadleywickham I very much enjoyed mine!

@juliesquid I like that one!

@CVWickham Time to Learn Data analysis in R Yours is still best...

@juliesquid Take a Leap and Dive into R

@qitaana 👋🏻 It was impossible to find anyone you were looking for. Next time?

Things I have done since #rstudioconf: 1. Sleep.
