It’s even predicted it will still be used in the year 2118! In this linear regression tutorial, we will explore how to create a linear regression in R, looking at the steps you'll need to take with an example you can work through. To easily run all the example code in this ...
Linear regression is simple, easy to fit, easy to understand, yet a very powerful model. We saw how linear regression could be performed on R. We also tried interpreting the results, which can help you in the optimization of the model. Once one gets comfortable with simple linear regression...
Plotting a scatter plot with a regression line in R Before I finish, I’ll quickly show you how to add a regression line onto a scatter plot, which is probably something you’re wanting to do. To plot a simple scatter plot, use the plot function. #Create a scatter plot plot(X, Y)...

In this tutorial I show you how to do a simple linear regression in R that models the relationship between two numeric variables. Check out this tutorial on YouTube if you’d prefer to follow along while I do the coding: The first step is to load some data. We’ll use the ‘trees’...
