For an hour or so earlier today Serious Stats was #1 in the amazon.co.uk sales rank for the category: Books > Health, Family & Lifestyle > Psychology & Psychiatry > Methodology > Statistics As of writing the rank has dropped to #3 (but I’m still quite excited – even though I know this may not imply large numbers of pre-orders). They have also […]
This blog and my other main blog (the companion blog for my book) are now syndicated via R-bloggers (posts tagged R only) and statsblogs.com. The latter is a relatively new blog aggregator but looks to have some interesting content. R-bloggers it quite...
Whilst writing the book the latest version of R changed several times. Although I started on an earlier version, the bulk of the book was written with 2.11 and it was finished under R 2.12. The final version of the R scripts were therefore run and checked using R 2.12 and, in the main, the most recent […]
UPDATE: Some problems arose with my previous host so I have now updated the links here and elsewhere on the blog. The companion web site for Serious Stats has a zip file with R scripts for each chapter. This contains examples of R code and and all my functions from the book (and a few extras). […]

This is a quick follow up to my earlier post that discussed how to graph CIs for within-subjects (repeated measures) ANOVA designs. My forthcoming book Serious stats describes how to do this for between-subjects designs (a much simpler proble...
I finally found some time to take a closer look at p curves. I haven't had a chance to follow-up my simulations (and probably won't for a few weeks if not months), but I have had time to think through the ideas the p curve approach raises based on some...
I have finally got around to posting the R code for my p curve simulation. Those familiar with R will realize how crude it is (I've been caught up with other urgent stuff and had no time to explore further).You are welcome to play with (and improve!) t...
Psych your mind has an interesting blog post on using p curves to detect dodgy stats in a a volume of published work (e.g., for a researcher or journal). The idea apparently comes from Uri Simonsohn (one of the authors of a recent paper on dodgy s...
I'm not a big fan of the term "nonparametric statistics", or at least how it is used in psychology and related fields (e.g., education and health research). This is one reason why I don't make a big deal of the parametric/non-parametric distinction in ...
