#statstab #492 A tiny review on e-values and e-processes
Thoughts: How to be a bayesian while wearing a frequentist hat.

#statstab #489 On the performance of the Neyman Allocation with small pilots
Thoughts: If you know your treatment condition will have larger variance you can optimise your sample size.

#statstab #477 Donβt calculate post-hoc power using observed estimate of effect size
Thoughts: Good discussion and many useful references. Even big journals print stupid stuff.

#statstab #470 Low power bias {shiny} app
Thoughts: easily show what conducting an underpowered study would do to your effect size (type M error).

#samplesize and #ethics question: You plan for a study needing n=100 (50 per cell). Power analysis is all set up and pre-reg. But, because you do research in a uni, you are told you need to allow for more participants (students) as there is a set number of credits all need to reach. What do you do?
#statstab #440 Computing Statistical Power for the Difference in Differences Design
Thoughts: DiD studies are all the rage in Obs research. But how does the concept of power apply to them?

#statstab #426 Execution of Replications
Thoughts: A good resource for conducting replications. Different ways to plan your sample size and consider "success/failure".

#statstab #421 Sample Size Planning for Statistical Power and Accuracy in Parameter Estimation
Thoughts: AIPE is based on controlling the width of the CI.
Sample size can be computed independent of effect size!

#statstab #371 Safeguard Power as a Protection Against Imprecise Power Estimates
Thoughts: tl;dr - when replicating a study, use the lower end of the CI of the original study as your effect in a power analysis.

Iβm here because I love debating with people who are so obtuse that they would be convinced that a player who has never performed at a major league level will suddenly start to perform at a major league level. #SampleSize.
Iβm giving a ten minute talk to #EMSky residents on #power and #samplesize analysis.
π§ What do you think we often get wrong on the topic?
