WebScatter plots are used to show relationships. For correlation, scatter plots help show the strength of the linear relationship between two variables. For regression, scatter plots often add a fitted line. In quality control, scatter plots can often include specification limits or reference lines. WebDec 23, 2024 · When we perform simple linear regression in R, it’s easy to visualize the fitted regression line because we’re only working with a single predictor variable and a single response variable. For example, the following code shows how to fit a simple linear regression model to a dataset and plot the results:

WebApr 9, 2024 · The diagonal line in the middle of the plot is the estimated regression line. Since each of the data points lies fairly close to the estimated regression line, this tells us that the regression model does a pretty good job of fitting the data. We can also create a data frame that shows the actual and predicted values for each data point:
