WebbThe values of R 2 are represented as a percentage ranging from 1 to 100 percent. R, R 2, and adjusted R 2 are different terminologies in statistics. R presents the correlation … WebbThe ratio of the variance or predicted to the variance of dependent variable is called R 2, and it's between 0 and 1 in OLS. It happens so that when you have only one independent variable R 2 = R, the Pearson correlation coefficient.

WebbR 2 compares the fit of the chosen model with that of a horizontal straight line (the null hypothesis). If the chosen model fits worse than a horizontal line, then R 2 is negative. Note that R 2 is not always the square of anything, so it can have a negative value without violating any rules of math.
