# Summary method for class "mkinfit"

### Description

Lists model equations, the summary as returned by `summary.modFit`

,
the chi2 error levels calculated according to FOCUS guidance (2006) as far
as defined therein, and optionally the data, consisting of observed, predicted
and residual values.

### Usage

1 2 3 4 |

### Arguments

`object` |
an object of class |

`x` |
an object of class |

`data` |
logical, indicating whether the data should be included in the summary. |

`distimes` |
logical, indicating whether DT50 and DT90 values should be included. |

`alpha` |
error level for confidence interval estimation from t distribution |

`digits` |
Number of digits to use for printing |

`...` |
optional arguments passed to methods like |

### Value

The summary function returns a list derived from
`summary.modFit`

, with components, among others

`version, Rversion` |
The mkin and R versions used |

`date.fit, date.summary` |
The dates where the fit and the summary were produced |

`use_of_ff` |
Was maximum or minimum use made of formation fractions |

`residuals, residualVariance, sigma, modVariance, df` |
As in summary.modFit |

`cov.unscaled, cov.scaled, info, niter, stopmess, par` |
As in summary.modFit |

`bpar` |
Optimised and backtransformed parameters |

`diffs ` |
The differential equations used in the model |

`data ` |
The data (see Description above). |

`start ` |
The starting values and bounds, if applicable, for optimised parameters. |

`fixed ` |
The values of fixed parameters. |

`errmin ` |
The chi2 error levels for each observed variable. |

`bparms.ode ` |
All backtransformed ODE parameters, for use as starting parameters for related models. |

`ff ` |
The estimated formation fractions derived from the fitted model. |

`distimes ` |
The DT50 and DT90 values for each observed variable. |

`SFORB` |
If applicable, eigenvalues of SFORB components of the model. |

The print method is called for its side effect, i.e. printing the summary.
