Chapter 3. Regression Analysis
Note
Learning Objectives
By the end of this chapter, you will be able to:
- Describe regression models and explain the difference between regression and classification problems 
- Explain the concept of gradient descent, how it is used in linear regression problems, and how it can be applied to other model architectures 
- Use linear regression to construct a linear model for data in an x-y plane 
- Evaluate the performance of linear models and use the evaluation to choose the best model 
- Use feature engineering to create dummy variables for constructing more complicated linear models 
- Construct time series regression models using autoregression 
Note
This chapter covers regression problems and analysis, introducing us to linear regression as well as multiple linear regression, gradient descent, and autoregression.
