R score ranges from - to 1. The closest to 1 the R , the better the regression model is. If R is equal to 0, the model is not performing better than a random model. If R is negative, the regression model is erroneous. Therefore this last Machine Learning Metric is an excellent tool to evaluate the efficiency of a regression model.
