This is *exactly* how I feel about generalised linear models. #statistics
Y'all know I'm right.
We need more idiots on mastodon.
Statistical illiteracy is a university promoting de facto citation rings among senior academics in the same institution and pretending those are independent observations when bragging about their top cited scientists.

The {tsbox} #rstats 📦 lets you work with time series data in any class:
* “Convert everything to everything - ts, xts, data.frame, data.table, tibble, zoo, zooreg, tsibble, tibbletime, timeSeries, irts or tis to each other“
* “ Helper functions make it easy to combine or align multiple time series of all classes”
* “Plotting all kinds of classes and frequencies is as simple as it should be. And we finally get a legend!”

Class-Agnostic Time Series

Time series toolkit with identical behavior for all time series classes: ts,xts, data.frame, data.table, tibble, zoo, timeSeries, tsibble, tis or irts. Also converts reliably between these classes.

Everybody's backyard

John Tukey said that the best thing about being a statistician is that you get to play in everyone’s backyard. It’s a great quote. While it more obviously reflects the tendency of applied statisticians (defined broadly) to be involved in lots of studies, it also captures something about statisticians that is often missed - that we are also scientists, delighted in the pursuit of new knowledge.

My 2 cents

🚨 preprint alert 🚨

Initial evidence that using #statcheck in peer review may reduce errors.

Results from a preregistered observational study of 7000+ psychology articles.

10 years after we created Registered Reports, the thing critics assured us would never (in a million years) happen has happened: @Nature is offering them.

The Registered Reports initiative just went up a gear and we are one step closer to eradicating publication bias and reporting bias from science.

Congratulations to all involved in achieving this milestone.

Nature welcomes Registered Reports

From this week, Nature will be publishing an additional type of research paper — designed to encourage rigour and replication.

Future generations will wonder why we did so little to prevent the next pandemic or to fight this one even as it still rages. https://www.nytimes.com/2023/02/22/opinion/bird-flu-pandemic-h5n1.html?searchResultPosition=1

America has failed to do all the things that might have secured lasting normalcy.

The New York Times
Some months ago after a Twitter exchange I learned some stuff about analysing simplex data - where the rows are constrained to add up to 1, data like soil composition, time use composition, etc. I have now written an #rstats blog post about what I have learned about the standard process of transforming, centering and rotating such data before visualisation or other analysis: http://freerangestats.info/blog/2023/02/25/ilr
Transformations for compositional data

I look into the use of Isometric Centralised Box-Cox Transformed Ratio for analysing compositional data like proportions of soil, time use or chemicals.
