Description Usage Arguments Details Value References Examples

This function finds the smallest relative error still resulting in passing the chi-squared test as defined in the FOCUS kinetics report from 2006.

1 | ```
mkinerrmin(fit, alpha = 0.05)
``` |

`fit` |
an object of class |

`alpha` |
The confidence level chosen for the chi-squared test. |

This function is used internally by `summary.mkinfit`

.

A dataframe with the following components:

`err.min` |
The relative error, expressed as a fraction. |

`n.optim` |
The number of optimised parameters attributed to the data series. |

`df` |
The number of remaining degrees of freedom for the chi2 error level calculations. Note that mean values are used for the chi2 statistic and therefore every time point with observed values in the series only counts one time. |

The dataframe has one row for the total dataset and one further row for each observed state variable in the model.
