June 13-15 Short Courses

Machine Learning/Predictive Modeling

Dr. Andrew Speer

Course Description

Organizational research often employs traditional statistical methods, such as linear regression, ANOVA, EFA, CFA, and SEM. However, these methods have limitations. They may not fully capture data complexity, overlook crucial relationships, or fail to optimally predict dependent variables. Additionally, traditional models can be overly complex, fitting well in the sample but failing to generalize to new, independent data due to potential chance capitalization. Machine learning algorithms address these limitations by avoiding underfitting (capturing complexity) and overfitting (cross-validating on new data). Predictive modeling forms, like random forests, LASSO regression, and neural networks, serve these purposes. These models complement traditional approaches in organizational research and may even replace them, especially when the number of variables exceeds the number of cases.This CARMA short course provides a hands-on experience using R and RStudio to analyze predictive models. If you’re unfamiliar with R basics, we recommend taking CARMA’s introductory R course. We’ll use available datasets and pre-developed R code to discuss, run, and interpret various machine learning models. Time permitting, we’ll explore methods to compare the performance of these models.

Meet the Instructor

Dr. Andrew Speer is an organizational scientist at Kelley School of Business at Indiana University. His research and consulting deal with employee selection, machine learning (e.g., bias audits for hiring methods using AI), individual differences at work (e.g., personality), and performance management.
