Webb13 apr. 2024 · A linear regression model is about finding the equation of a line that generalizes the dataset. Thus, we only need to find the line's intercept and slope. The regr_slope and regr_intercept functions help us with this task. Let’s suppose we have a table with the rainfall and temperature columns.
