Cross Validation
The video below talks about the idea of cross validation (CV). This is a method of evaluating a predictive model while not necessarily needing to split the data into a training and test set (although sometimes we will still do this and just apply CV on the training set).
I highly recommend watching the video using the ‘full’ Panopto player. There is a ‘pop out’ button in the bottom right of the video to enter this viewer.
