Whether you’re an entrepreneur or freelancer, or whether you’re the founder of a start-up looking to scale your business, you will discover that you need relationships to survive. We need people to lean on in times of adversity and lost hope. We need people to coach and mentor us when we don’t know the way. We need people to open doors for us that otherwise would remain closed.

In this type of cross validation, the number of folds (subsets) equals to the number of observations we have in the dataset. We then average ALL of these folds and build our model with the average. We then test the model against the last fold. Because we would get a big number of training sets (equals to the number of samples), this method is very computationally expensive and should be used on small datasets. If the dataset is big, it would most likely be better to use a different method, like kfold.
