# Print Exit Information for gnm Fit

### Description

A utility function to print information on final iteration in
`gnm`

fit, intended for use when `gnm`

has not converged.

### Usage

1 | ```
exitInfo(object)
``` |

### Arguments

`object` |
a |

### Details

If `gnm`

has not converged within the pre-specified maximum
number of iterations, it may be because the algorithm has converged to
a non-solution of the likelihood equations. In order to determine
appropriate action, it is necessary to differentiate this case from
one of near-convergence to the solution.

`exitInfo`

prints the absolute score and the corresponding
convergence criterion for all parameters which failed to meet the
convergence criterion at the last iteration. Clearly a small number of
parameters with scores close to the criterion suggests
near-convergence.
