Calculates the functional MRD for a fitted FDboost-object

1 |

`object` |
fitted FDboost-object with regular response |

`overTime` |
per default the functional MRD is calculated over time
if |

`breaks` |
an optional vector or number giving the time-points at which the model is evaluated. Can be specified as number of equidistant time-points or as vector of time-points. Defaults to the index of the response in the model. |

`global` |
logical. defaults to |

`...` |
currently not used |

Formula to calculate MRD over time, `overTime=TRUE`

:

* MRD(t) = n^{-1} ∑_i |Y_i(t) - \hat{Y}_i(t)| / |Y_i(t)| *

Formula to calculate MRD over subjects, `overTime=FALSE`

:

* MRD_{i} = \int |Y_i(t) - \hat{Y}_i(t)| / |Y_i(t)| dt \approx G^{-1} ∑_g |Y_i(t_g) - \hat{Y}_i(t_g)| / |Y_i(t)|*

Returns a vector with the calculated MRD and some extra information in attributes.

`breaks`

cannot be changed in the case the `bsignal()`

is used over the same domain
as the response! In that case you would have to rename the index of the response or that
of the covariates.
