R2 of 0

WebHere are some basic characteristics of the measure: Since r 2 is a proportion, it is always a number between 0 and 1.; If r 2 = 1, all of the data points fall perfectly on the regression line. The predictor x accounts for all of the variation in y!; If r 2 = 0, the estimated regression line is perfectly horizontal. The predictor x accounts for none of the variation in y! The coefficient of determination (R²) measures how well a statistical model predicts an outcome. The outcome is represented by the model’s dependent variable. The lowest possible value of R² is 0 and the highest possible value is 1. Put simply, the better a model is at making predictions, the closer its R² will be to … See more You can choose between two formulas to calculate the coefficient of determination (R²) of a simple linear regression.
