Preprocessing, there are many variables with only 1 level, and even more without any entries.The ‘nzv’ command does not remove the variables with more than 10% missing or NA values. A function to drop all columns with corrupted data, missing values and NA’s may help create a cleaner data set.
There are still many columns with missing, corrupt or NA values, choosing variables so that the models can be run on the data:
Cross-validation on the cleaned training set, to evaluate the accuracy of the out of sample error (in the test data set).
Step one is dividing the training set into training and test sets Step two is setting the number of K-folds Step three is running a model on the training data set, using the number of K-folds selected in step one Step four is running the model on the “training-testing” dataset
