Final Words

Again, before finishing the module I would like to give you some insights into the main concepts you should have become familiar with.

1. It is important to know how to work with the formula argument. Most modeling tools available in R use this kind of argument.

2. Mastering data manipulation and sampling is a must.

3. Distiguishing between calibration and validation samples is also mandatory.

4. You should begin to become familiar with model calibration and variable selection for model fitting, ie, retrieving the best parameters for our model on the basis of the validation.
