Here's a new paper summarizing methods for evaluating whether the absence of a statistically significant difference (from a NHST) is actually no difference--test of equivalence, confidence interval bounds, likelihood ratios, Bayes factors, and Bayesian estimation. There's nothing new here, but it's a nice readable overview that might be worth citing for some audiences.

New on the blog: I explore the connection between Bayes factors and cross-validation and explain why I think it does not justify the use Bayes factors in most cases. https://www.martinmodrak.cz/2024/03/23/cross-validation-a-fourth-way-to-compute-a-bayes-factor/

Was going through old repositories; found this nice document on estimating treatment effect of a medicine for a single patient with seizures #rstats :rstats:
It goes from simple to complex:
- #Visualization & summary statistics
- Poisson regression (glm) with a treatment dummy
- Penalized poisson regression to deal with 0s
- Correcting for autocorrelation
- #Bayesian Poisson model with #stan #rstanarm
- Correcting for autocorrelation and #BayesFactors #bridgesampling
