About Me

I am an #rstats and open science enthusiast. I currently work at Utah State University as a Research Assistant Professor. I serve as a methodologist on several research teams, and develop accessible data tools. This site contains my blog and other open resources for learning data analysis.

Using Jamovi: Logistic Regression

This post is part of a series–demonstrating the use of Jamovi–mainly because some of my students asked for it. Notably, this is using version 0.8.6.0. Today’s topic is logistic regression (with a binary outcome).

Using Jamovi: Correlation and Regression

This post is part of a series–demonstrating the use of Jamovi–mainly because some of my students asked for it. Notably, this is using version 0.8.6.0. Today’s topic is correlation and linear regression.

Using Jamovi: Introduction

Jamovi is a new piece of software that makes running most basic analyses quicker, easier, and better. Shockingly, this is a free program based on the R programming language. It has the goal of “free and open software to bridge the gap between researcher and statistician.” Needless to say, it is worth taking a look if you are doing some basic analyses and don’t want to pay for SPSS or SAS, or learn how to use R. It provides informative tables and neat visuals.

Using the afex R package for ANOVA (factorial and repeated measures)

We recently switched our graduate statistics courses to R from SPSS (yay!). It has gone fairly well. However, once we get into ANOVA-type methods, particularly the repeated measures flavor of ANOVA, R isn’t as seamless as almost every other statistical approach. As such, my colleague Sarah Schwartz found the afex package that looks like it can be helpful in simplifying the code and increasing the amount of useful information obtained.

Writing Your Dissertation (or Thesis) in RMarkdown

A few days ago I announced that I had completed the requirements for a PhD in Quantitative Psychology and (maybe more interestingly) that I had written my entire dissertation in Rmarkdown. It was more of a shoutout to @RStudio but the interest in how I did it was exciting.

Recent Accepted Paper in the R Journal

Recently, our paper Furniture for Quantitative Scientists was posted in the R Journal. This paper discusses the use of descriptive statistics in exploring data through the furniture package. See the R Journal for the manuscript.
