High r square means

R is a measure of the goodness of fit of a model. In regression, the R coefficient of determination is a statistical measure of how well the regression predictions approximate the real data points. An R of 1 indicates that the regression predictions perfectly fit the data. Values of R outside the range 0 to 1 occur when the model fits the data worse than the worst possible least-squares predictor (equivalent to a horizontal hyperplane at a height equal to the me… 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. The first formula is specific to simple linear regressions, and the … See more You can interpret the coefficient of determination (R²) as the proportion of variance in the dependent variable that is predicted by the statistical model.
