BayesFactorExtras: a sneak preview
Felix Schönbrodt and I have been working on an R package called BayesFactorExtras. This package is designed to work with the BayesFactor package, providing features beyond the core BayesFactor functionality. Currently in the package are:Sequential Bayes factor plots for visualization of how the Bayes factor changes as data come in: seqBFplot()A...

At the APS Observer: a profile of JASP
The APS Observer has just published a profile of JASP, a graphical user interface designed to make statistics easier. It includes Bayesian procedures by means of the R and the BayesFactor package. From the article: JASP distinguishes itself from SPSS by being as simple, intuitive, and approachable as possible, and by making accessibl...

How to shoot yourself in the foot with various statistical philosophies
I’ve long been a fan of “How to shoot yourself in the foot” jokes. Having shot myself in the foot with different programming languages — particularly with C — I was thinking about how one might shoot oneself in the foot with various statistical approaches. So, here we go…Subjective Bayesianism (de Finetti): Believe you�...

The frequentist case against the significance test, part 2
The significance test is perhaps the most used statistical procedure in the world, though has never been without its detractors. This is the second of two posts exploring Neyman’s frequentist arguments against the significance test; if you have not read Part 1, you should do so before continuing (“The frequentist case against the significance...

How to check Likert scale summaries for plausibility
Suppose you are reading a paper that uses Likert scale responses. The paper reports the mean, standard deviation, and number of responses. If we are — for some reason — suspicious of a paper, we might ask, “Are these summary statistics possible for this number of responses, for this Likert scale?” Someone asked me this recentl...
