perlatex Use the base pipe `->.;` from R version 3 and upwards.

Should we use findings from previous studies and meta-analyses to shape our statistical inferences (aka informed priors)? What are the advantages and issues? Strap on for a loooong thread (link to a video of the talk at the end) 1/

#Statistics thought of the day: If you use Bayesian methods for design & analysis of #clinicaltrials it's because you want completely different probabilities than what frequentists compute. Don't ask a Bayesian trial to compute alpha hbiostat.org/bbr/alpha.html #StatThink

Terrific new intro to Bayesian approaches in drug development by Steve Ruberg and colleagues: nature.com/articles/s4157… #Statistics #biostatistics #clinicaltrials #Pharmaceutical @vandy_biostat @EdgeforScholars

New #rstats package qreport is now on CRAN, facilitating statistical reports/books/web sites using Quarto, implementing things like dynamic tabs and composition of full report sections (e.g. missing data report & data overview). hbiostat.org/R/qreport #rstats @vandy_biostat

Wonderful new paper on serious problems with standard confidence interval for a probability. Why are we still using it as opposed to the Wilson interval (or better: Bayes) tandfonline.com/doi/full/10.10…

A clue to what makes countries rich. And this is on a log scale.

We have created new tutorials for Bayesian SEM with the package blavaan, on topics like - modification indices - prior predictive checks - probability of direction - model comparison .. and more @edgarmerkle #blavaan #RStats #bayes #SEM ecmerkle.github.io/blavaan/

Kinds of Bayesians the definitive list Subjective: Priors represent personal beliefs Objective: Really frequentists Affective: Priors are vibes Effective: Just want model to converge Elective: Just likes Markov chains Defective: The rest of us

In honour of #EAM2023, I'm giving away one copy of 'Computational Aspects of Psychometric Methods. Using #RStats'. To enter, follow me & RT by Sunday 7/16 night. I'll randomly pick the winner and DM for delivery. @Eam2023
