Multilevel Modeling Workshop Materials

Many thanks to Rutgers University Spanish and Portuguese Department ( for asking me to come talk about multilevel models. I enjoyed talking to the group, meeting Twitter friends in real life!, and I am especially impressed by what their department is doing in what is often considered a qualitative science. I used RStudio’s Cloud to share a workspace with all the materials, packages, and other information you might need. I built the slide show using markdown, so that people could watch the slides and/or take their own notes. [Read More]

Updating Your CV with Packages

Hi guys! I have finally done it! I updated my CV with Rmarkdown using Steve’s Markdown Templates. I was tempted to use the new vitae package, but I had already gone down this path before that came out, just finally getting back to it. Link to the entire CV folder for you to use/view do stuff with: CV. Please ignore the html files in that folder, it does “knit” automatically as part of the website build using markdown - you should be using PDF and LaTex for the CV part. [Read More]

Line Endings Are Dumb

I have happily acquired a new Mac Book (yay!) and a new work computer (Windows). So, I’ve been making One Drive exceedingly unhappy moving GBs of file from one to another. As I was working on reconnecting my GitHub repositories to the files, I was trying to understand why several of my repos were saying I had a bunch of file changes but nothing in the files themselves had changed. I noticed they were mostly . [Read More]

Intuitions about Grades

Are my intuitions about grades correct? I was recently talking to a colleague about how utterly terrible my students were doing in my online class this semester and that nearly half were failing the class. We are in our last week of the semester, and I am completely over packing, so I thought I would examine if the judgments I had made about this semester are accurate. First, I took all the times I had taught memory and cognition post Ph. [Read More]

JASP Videos + Guides

Hey everybody! I am back and finally getting to videos again. I hesistate to say “it’s been crazy!” because I feel like that’s always a thing that academics say, but I will say I’ve had a lot of life going on, and I am finally getting back to a normal amount of crazy. I’ve decided to do some simple videos to start - so I am creating how-to videos to go with our JASP guides we created this summer. [Read More]

Quick and Dirty Categorical lavaan

I was tagged today on twitter asking about categorical variables in lavaan. I will say I have not done much with categorical predictors either endogenous or exogenous. I did a quick reproducible example of exogenous variables, and I will refer you to the help guide for lavaan here. You will need both the lavaan and psych packages to reproduce this code. Ironically, this data is binary outcome data (the epi dataset in psych), which wasn’t intentional, I just knew it was a good dataset to work with to test how to do exogenous categorical variables.

Current Publications with Papaja

Heyo! Frederik, the author of papaja, requested that we update him with papers written with his package. I was like, oh man, like the whole lab?! So, I decided that I could probably make it easy by making a table here. Obviously, this table is current at the moment, as I hope many of the ones under review will get accepted, and I have several others that we will start writing soon. [Read More]

Gathering Text from the Web

Hi everyone! I don’t really feel like working too hard today, so I decided to write a blog post about how my student Will and I used rvest to mine articles from several different news sources for a project. All the scripts and current ongoings of this project can be found on our OSF page - this project is also connected to the GitHub folder with the files. First, we picked four web sources to scrape - The New York Times, NPR, Fox News, and Breitbart because of their known political associations, and specifically, we focused on their political sections.
