Correlation between two lines
WebJul 27, 2024 · Linear regression is an approach to model the relationship between a single dependent variable (target variable) and one (simple regression) or more (multiple regression) independent variables. The linear regression model assumes a linear relationship between the input and output variables. WebHere are four points to try it with that make the calculation not too bad: Put these in the formula and you should get r = 0.891, a quite high correlation. Conversely, pick any four points that make a horizontal rectangle, for example (2, 2), (8, 2), (2, 6), (8, 6). If you calculate r for these points, it will be 0.
