Web1.6 - (Pearson) Correlation Coefficient, r. The correlation coefficient, r, is directly related to the coefficient of determination R 2 in an obvious way. If R 2 is represented in decimal form, e.g. 0.39 or 0.87, then all we have to do to obtain r is to take the square root of R 2: r = ± R 2. The sign of r depends on the sign of the estimated ... WebThe Pearson correlation coefficient, r, can take a range of values from +1 to -1. A value of 0 indicates that there is no association between the two variables. A value greater than 0 indicates a positive association; that is, as the value of one variable increases, so does the value of the other variable.
WebR-squared measures how much prediction error we eliminated Without using regression, our model had an overall sum of squares of 41.1879 41.1879. Using least-squares regression reduced that down to 13.7627 13.7627. So the total reduction there is 41.1879-13.7627=27.4252 41.1879−13.7627 = 27.4252.
