Proud to be a co-author with Rasha Al-Lamee Matthew Shun-Shin on a 100% Bayesian clinical trial paper that also uses our latest longitudinal ordinal modeling approach, helped by the rmsb package: thelancet.com/journals/lance… How can cardiologist Matthew Shun-Shin master all this?

What an amazing time together with two of my all-time favorite collaborators, from Imperial College London, Matthew Shun-Shin and Rasha Al-Lamee coupled with fun discussions about clinical trial design, outcome measures, Bayes, and more.

This is a must-see on many levels. While watching it I became frightened at how things are so similar in my field of especially related to Sabine Hossenfelder 's comment 'They just wanted to write papers', plus how fad-driven is .

throught of the day: If sponsors knew how much money was wasted with fixed sample size designs, and how much earlier Bayesian sequential designs would have bailed out on ineffective treatments, they'd be shocked. hbiostat.org/bayes/bet/desi…

This blog article has been much improved with several more examples of assumptions made by various methods, and making a distinction between faux-nonparametric methods like Wilcoxon and log-rank, and true nonparametric methods like Kolmogorov-Smirnov. Vanderbilt Department of Biostatistics

What on earth is the point in obsessing about non- collapsibility of odds ratios whilst failing to observe that the 'binary' outcome is actually an arbitrary dichotomy.

Another great paper pointing out why the model used to analyze should adjust for a superset of stratification information.

software discovery of the day: When using Quarto to produce a Word .docx file containing LaTeX math in it, the Word file perfectly renders the equations and they are editable using LaTeX syntax in Word. Didn't know that. The equations don't display on iPad though.
