Psychological Statistics: 2021

A quick overview of the egocentric relation event model (EREM) with linked examples in R: part 1

This post is based on an interdisciplinary collaboration (between anthropologists and psychologists) with Kate Ellis-Davies and Sheina Lew-Levy (who initiated the project), Eleanor Fleming and Adam Boyette. The work was recently published in Field Methods and is available here: Demonstrating the Utility of Egocentric Relational Event Modeling Using Focal Follow Data from Congolese BaYaka Children and Adolescents Engaging in Work and Play. I led on the statistical modeling of the data including adapting the implementation for focal follow data (which I'll explain more about in part 2) with the other authors contributing knowledge of the theory and literature (as we were keen to ensure that we demonstrated the approach using real data addressing a substantive research question).

I Will Not Ever, NEVER Run a MANOVA

I have been thinking to write a paper about MANOVA (and in particular why it should be avoided) for some time, but never got round to it. However, I recently discovered an excellent article by Francis Huang that pretty much sums up most of what I'd cover. In this blog post I'll just run through the main issues and refer you to Francis' paper for a more in-depth critique or the section on MANOVA in Serious Stats (Baguley, 2012).

A brief introduction to logistic regression

I wrote a brief introduction to logistic regression aimed at psychology students. You can take a look at the pdf here:

A more comprehensive introduction in terms of the generalised linear model can be found in my book:
