k-Fold Cross-Validation

This video provides a conceptual overview of k-fold cross-validation, which is a useful for framework for training models and evaluating predictive performance/accuracy. To learn how perform k-fold cross-validation using R, check out this video where I demonstrate using a logistic regression model: https://youtu.be/BQ1VAZ7jNYQ?si=FyskPZZVqvMTIL41 For a written tutorial of how to perform k-fold cross-validation using R using a logistic regression model, check out my free ebook: https://rforhr.com/kfold.html For a conceptual overview of statistical and empirical cross-validation techniques, check out this video: https://youtu.be/DWUc5GBRFuA?si=etEfhiONMokkVg5C
