As you'll see, by using computing and concepts from machine learning, we'll be able to leapfrog many of the marginal and esoteric topics encountered in traditional 'regression' courses.<p> <a href="https://www.datacamp.com/courses/statistical-modeling-in-r-part-2">The intermediate course</a> will get you up to speed with the most important and powerful methodologies in statistics.</p>

- 1
### What is statistical modeling?

**Free**This chapter explores what a statistical model is, R objects which build models, and the basic R notation, called

*formulas*used for models. - 2
### Designing, training, and evaluating models

In this chapter, you'll start building models: specifying what variables models should relate to one another and training models on the available data. You'll also provide new inputs to models to generate the corresponding outputs.

- 3
### Assessing prediction performance

This chapter is about techniques for deciding whether an explanatory variable improves the prediction performance of a model. You'll use cross validation to compare different models.

- 4
### Exploring data with models

This chapter is about constructing models to explore masses of data, for instance to generate hypotheses about what factors are important in how a system works. You'll see how the recursive partitioning model architecture, which has an internal logic for selecting explanatory variables, can be used to explore potentially complex relationships among variables. The chapter also covers the evaluation of prediction performance in models where the response variable is categorical, that is, models used for classification.

- 5
### Covariates and effect size

Real-world systems are complicated. To faithfully reflect that complexity, models can incorporate multiple explanatory variables. This chapter introduces the notion of

*covariates*and how they allow you to model the effect of an explanatory variable while taking into account the effects of other variables.

“I've used other sites—Coursera, Udacity, things like that—but DataCamp's been the one that I've stuck with.”
