Next up: @markjrieke is Introducing work boots: generate prediction intervals from tidymodels workflows #RStudioConf2022 #RStudioConf #RStats Mark Rieke prepares to present his workboots package.
Xgboost can't generate prediction intervals. workboots lets you add them (I missed the photo of his slide with intervals, he tweeted a link to his slides, I'll add that in a sec) #RStudioConf2022 #RStudioConf #RStats A plot of xgboost predictions, with just points (no interval
Point estimates don't give the whole picture. #RStudioConf2022 #RStudioConf #RStats
workboots lets you use powerful models but also get prediction intervals via bootstrapping #RStudioConf2022 #RStudioConf #RStats Workboots sitting between simple models (which have their ow
To use workboots make sure you have:
Normally distributed residuals
Time to run it (it takes longer, slow models might be too slow)
An actual need for the fancy package. #RStudioConf2022 #RStudioConf #RStats workboots checklist  ✔ Normally distributed residuals  ✔
I recommend clicking through to the slides for the code examples. You can add ranges to predictions and also generate (ranges of) feature importance. #RStudioConf2022 #RStudioConf #RStats

Now that #RStudioConf2022 is over and I've had some time to process, it's time for a 🧵 to look back and summarize my copious notes. Hopefully this can be useful to someone other than just me! #RStudioConf #RStats #PyData
Before the conf proper, I TAed the 🔮 {tidymodels} workshop. Because @rstudio / #Posit are who they are, all workshop materials are free and open via github.com/rstudio/rstudi… (github.com/rstudio-conf-2… in case that link ever breaks) #RStudioConf2022 #RStudioConf #RStats
#RStudioConf2022 proper kicked off with a pre-keynote announcement from @fly_upside_down & @hadleywickham. As you've probably heard, @rstudio is now #Posit 💭. My thread (with old hashtag):
