An estimate of *σ*, the estimated standard deviation of the error term in the model. Note that *s*^{2} is the variance component for error.

R^{2} is also known as the coefficient of determination.

Term | Description |
---|---|

y _{i} | i ^{th} observed response value |

mean response | |

i ^{th} fitted response |

While the calculations for adjusted R^{2} can produce negative values, Minitab displays zero for these cases.

n | number of observations |
