WebbAn R 2 of 1.0 indicates that the data perfectly fit the linear model. Any R 2 value less than 1.0 indicates that at least some variability in the data cannot be accounted for by the model (e.g., an R 2 of 0.5 indicates that 50% of the variability in the outcome data cannot be explained by the model). WebbIf the value of r 2 gets close to 1, The values of y become close to the regression line and similarly if it goes close to 0, the values get away from the regression line. It helps in determining the strength of association between different variables. Steps to Find the Coefficient of Determination.

But there are special cases: •R2equals 1.00 when the curve goes through every point. But if you have replicate Y values at the same X value, it is impossible for the curve to go through every point, so R2has to be less than 1.00. floodwise property mapWebbSimply put, high R^2 values are NOT necessarily a sign of bad model choices.
