Linear Regression through the Origin

The linear regression models examined so far have always included a constant that represents the point the regression line crosses the y-axis, called the intercept. However, there are some cases...

Linear Regression Confidence and Prediction Intervals

In a previous example, linear regression was examined through the simple regression setting, i.e., one independent variable. Fitting a linear model allows one to answer questions such as: What is the...

Simple Linear Regression Models with R

Linear regression is a widely used technique to model the association between a dependent variable and one or more independent variables. In the Simple Linear Regression setting, which is what...
