LASSO Regression in R (Part One)

In Part One of the LASSO (Least Absolute Shrinkage & Selection Operator) regression tutorial, I demonstrate how to train a LASSO regression model in R using k-fold cross-validation using training data and how to evaluate the final model using hold-out test data. You can find Part Two here: https://youtu.be/NUfbl7ijZ0Q. For a conceptual overview of LASSO regression, please see the following video: https://youtu.be/hZHcmLW5JO8.
