This function provides rho-squared (also called McFadden's R-squared or pseudo R-squared), rho-squared adjusted by the number of estimated coefficients, the number of estimated coefficients, and log likelihood values at the start and at convergence.

In version 0.3-0 and later versions, this function is also available for calculating goodness-of-fit measures for binary choice models estimated by using the function `glm`

in the package stats.

This function returns an object of S3 class "gofm" that is a list with the following components.

`RHO2` |
The rho-squared value. Defined as |

`AdjRHO2` |
The rho-squared value adjusted by the number of estimated coefficients. Defined as |

`AIC` |
The Akaike Information Criterion (AIC). |

`BIC` |
The Bayesian Information Criterion. |

`K` |
The number of estimated coefficients. |

`LL0` |
The log likelihood value at the start. |

`LLb` |
The log likelihood value at convergence. |
