- This tutorial demonstrates how to perform k-fold cross-validation in R. Binary logistic regression is used as an example analysis type within this cross-validation method. Beyond the context of training supervised statistical learning models (e.g., LASSO regression), cross-validation approaches like k-fold cross-validation are useful for evaluating the predictive performance/accuracy of more conventional statistical models, such as ordinary least squares (OLS) linear regression or generalized linear models.
For a conceptual overview of k-fold cross-validation, please see the following video: • k-Fold Cross-Validation .
