An estimate of σ, the estimated standard deviation of the error term in the model. Note that s2 is the variance component for error.
R2 is also known as the coefficient of determination.
Term | Description |
---|---|
yi | i th observed response value |
mean response | |
i th fitted response |
While the calculations for adjusted R2 can produce negative values, Minitab displays zero for these cases.
