Replication report: Multilevel-Linear-Models using SAS and SPSS for repeated measures designs

The following is a report on the reproduction of the statistical work in the paper “Differences of Type I error rates for ANOVA and Multilevel-Linear-Models using SAS and SPSS for repeated measures designs" by Nicolas Haverkamp and André Beauducel at the University of Bonn.

Reversi in R - Part 2: Graphics and Custom Boards

In this post, I finish the Reversi / Othello game in R by improving the graphics, adding the ability to save and load boards, and fixing bugs. Also, many more boards have been added and tested, including those with unusual shapes, three or more players, and walls that can make the board into unusual shapes or even break it in half.

Reading questions: Struck by Lightning

The book Struck by Lightning, by Jeffery Rosenthal hits that balance of scientific correctness and approachability just right for a general audience book on probability. It’s been in print for 14 years now, and was a Canadian bestseller, so there’s nothing new that would come from a traditional review and therefore I won’t write one.

Instead, two points:

1.      It should be required K-12 or 100-level math/stats reading.

Reversi in R - Part 1: Bare Bones

In this post, I showcase a bare-bones point-and-click implementation of the classic board Reversi (also called Othello*) in the R programming language. R is typically used for more serious, statistical endeavors, but it works reasonably well for more playful projects. Building a classic game like this is an excellent high-school level introduction to programming, as well as a good basis for building and testing game AI.

I read this: New Rules for Classic Games

New Rules for Classic Games, by R. Wayne Schmittberger, written in 1992, is exactly what it sounds like. "New Rules" contains possible amendments to rules for Risk, Monopoly, Poker, Bridge, Scrabble, Reversi/Othello*, Shogi, Go, and of course Chess.

Annual Report to Stakeholders 2018-19

Every year in grad school I had to write a report on my research and academic progress. I found it a useful exercise so I've continued to do so as a faculty member and post-doc.

Summary: 

Professionally, this year was a struggle just to keep my head above water. I expect next year to be more productive in general, as well as more research oriented.

Replication Report - Informative Priors and Bayesian Updating

The following is a report on the reproduction of the statistical work in the paper "The use of informative priors and Bayesian updating: implications for behavioral research" by Charlotte O. Brand et al.

The original paper was accepted for publication by Meta-Psychology, https://open.lnu.se/index.php/metapsychology, a journal focused on methodology and reproductions of existing work. This report continues my attempt to establishing a standard for replication reports according to the Psych Data Standards found here https://github.com/psych-ds/psych-DS
