Model comparison via Bayes Factor analysis
Results of Bayesian analyses can be utilised for future research in the sense of Dennis Lindley’s motto: “Today’s posterior is tomorrow’s prior” (Lindley, 1972), or as Richard Feynman put it “Yesterday’s sensation is today’s calibration” to which …
P-rep: A misguided proposal to rescue the p-value
The primary objective of prep is to provide an estimate of replicability (based on the empirical data) which does not involve Bayesian assumptions with regards to a priori distributions of θ. The submission guidelines of the APA flagship journal …

The p-value ritual
***
The Aristotelian syllogistic logic behind the Fisherian p-value is ubiquitously misunderstood. This can lead to various fallacious logical inferences. The p-value resembles a Kantian paralogism, i.e., the metric appears objective and logically valid, even though it is …
