This week’s #TidyTuesday dataset is all about Doctor Who, celebrating the upcoming new episodes, and this screencast walks through how to use empirical Bayes to estimate ratings for different episode writers. The great thing about empirical Bayes is we can take into account the number of episodes each writer wrote.

Sometimes copilot feels more like a burden than a companion. Thanks Julia, I always learn a ton with these videos.

Interesting! Could you do more practical applications of Bayesian statistics. I see it more and more asked and required by bigger tech companies.

Great episode like always Just a little whim from my side: would you mind doing videos about TDA real-life application ? And how can implement Spark on models that aren't on Parnsip ? Thank you 😅

Hey Julia, thanks for you video ! I really like these.. I had one question about the std_var per writer... why did you divided it by the number of observations ?

Hey hi, it's cos the standard error of the average is sigma/sqrt(n), so the variance of the average would be sigma^2/n

(I'm very very new to all this) Getting the prior and the empirical/posterior from the same data seems counterintuitive to me and a bit like confirmation bias.

If you'd like some more conceptual background and theory behind this, I recommend the writing that Bradley Efron has done on it, the 1985 paper by Casella, and, for a more practical approach, the book _Introduction to Empirical Bayes: Examples from Baseball Statistics_ by my collaborator David Robinson.

YES! This is evidence supporting my hypothesis that Jodie Whittaker is a great actress, but Chris Chibnall is a terrible writer 😅. It isn't conclusive obviously. We would need observations from when they worked separately to get better proof.

Hey Julia. Writing you here although its not related to this specific video. I am using the tidylo::bind log odds for a project but the fact that the order of set/feature is different than the one in tidytext::bind tf idf (which requires term and then document) makes it hard to easily encode it for shiny (with f

Can you open an issue over at tidylo with an example/reprex showing what you mean? github.com/juliasilge/tidylo/issues

The extra brackets of copilot can be really annoying! When I turn it on I've started to use enter for RStudio's autocomplete (tab just takes copilot's often incorrect suggestion), does anyone have a better solution?

Looks like the RStudio team is tracking the extra parentheses here: github.com/rstudio/rstudio/issues/13953 Feel free to thumbs up or add additional detail!
