I’m not going to focus on the Call, Residuals, or Coefficients section. Multiple R-squared: 0.7477,Ědjusted R-squared: 0.6846į-statistic: 11.85 on 2 and 8 DF, p-value: 0.004054 Meaning Behind Each Section of Summary() Residual standard error: 1.141 on 8 degrees of freedom Now, we’ll create a linear regression model using R’s lm() function and we’ll get the summary output using the summary() function. Just for fun, I’m using data from Anscombe’s quartet (Q1) and then creating a second variable with a defined pattern and some random error. #Some fake data, set the seed to be reproducible. To follow along with this example, create these three variables. Getting Started: Build a Modelīefore we can examine a model summary, we need to build a model.

In addition, I’ll also show you how to calculate these figures for yourself so you have a better intuition of what they mean. I’m going to explain some of the key components to the summary() function in R for linear regression models.

However, when you’re getting started, that brevity can be a bit of a curse. R’s lm() function is fast, easy, and succinct. Takes into account number of variables and observations used.
