optional variance measure (for p>n) |

Additional arguments for summary generic |

An anova summary is produced, with Df, RSS and Cp for each step. Df is tricky for some models, such as forward stagewise and stepwise, and is not likely to be accurate. When p>n, the user is responsible for supplying sigma2.

An anova object is returned, with rownames the step number, and with components:

`Df ` |
Estimated degree of freedom |

`Rss` |
The Residual sum of Squares |

`Cp` |
The Cp statistic |
