Introducción a la regresión lineal
- What Is a Linear Regression Model?
Regression models describe the relationship between a dependent variable and one or more independent variables. - Linear Regression
Fit a linear regression model and examine the result. - Stepwise Regression
In stepwise regression, predictors are automatically added to or trimmed from a model. - Reduce Outlier Effects Using Robust Regression
Fit a robust model that is less sensitive than ordinary least squares to large changes in small parts of the data. - Choose a Regression Function
Choose a regression function depending on the type of regression problem, and update legacy code using new fitting functions. - Summary of Output and Diagnostic Statistics
Evaluate a fitted model by using model properties and object functions. - Wilkinson Notation
Wilkinson notation provides a way to describe regression and repeated measures models without specifying coefficient values.

- Partial Least Squares
Partial least squares (PLS) constructs new predictor variables as linear combinations of the original predictor variables, while considering the observed response values, leading to a parsimonious model with reliable predictive power. - Partial Least Squares Regression and Principal Components Regression
Apply partial least squares regression (PLSR) and principal components regression (PCR), and explore the effectiveness of the two methods.
