This will reset the permalinks and fix the issue in many cases. Next, we can plot the data and the regression line from our linear regression model so that the results can be shared. In this model we have only one variable so the p-value is exactly the same. In the Normal Q-Qplot in the top right, we can see that the real residuals from our model form an almost perfectly one-to-one line with the theoretical residuals from a perfect model.
