Chapter 14. Cross-validation and Bootstrapping Using Caret and Exporting Predictive Models Using PMML
In Chapter 12, Multilevel Analyses, we examined how to fit and predict nested data using multilevel analyses. In the previous chapter, we discussed text mining in R. In this chapter, we will discover how to perform cross-validation and bootstrapping using the caret
package and how to export models using Predictive Model Markup Language (PMML).
