As Thom says, power is strictly a frequentist concept, but there still is a relatively big literature on sample size determination in Bayesian context and so Bayesian power analysis is "a thing" in practice. Kruschke's 2013 is a good place to start: jkkweb.sitehost.iu.edu/articles/Kru...

Interact with Bluskey in R using the atrrr package. E.g, get your followers and followees:

library(atrrr)
my_handle <- 'username'
auth(user = my_handle, password = 'password')
my_followers <- get_followers(actor = my_handle, limit = Inf)
my_followees <- get_follows(actor = my_handle, limit = Inf)

S7 0.2.0 - Tidyverse S7 is a new package that simplifies object-oriented programming (OOP) in R. It combines the simplicity of S3 with the structure of S4 to create a clearer system that's accessible to everyone.

S7 0.2.0 is now on CRAN, thanks primarily to the hard work of @t-kalinowski.bsky.social. S7 is a collaborative effort to supersede S3 and S4 and you can read all about it (and what's new in 0.2.0) at www.tidyverse.org/blog/2024/11... #rstats

You can open any high quality medical journal and read authors talking about "trends" in estimates, almost always when the attached p-value is just outside the "significance" cutoff. This kind of thing is maddening, because it simply doesn't reflect reality. It's not just wrong, it's...stupid 😬. 1/
