Calculates the functional MSE for a fitted FDboost-object

1 2 |

`object` |
fitted FDboost-object |

`overTime` |
per default the functional R-squared 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 |

`relative` |
logical. defaults to |

`root` |
take the square root of the MSE |

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

:

* MSE(t) = n^{-1} ∑_i (Y_i(t) - \hat{Y}_i(t))^2 *

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

:

* MSE_i = \int (Y_i(t) - \hat{Y}_i(t))^2 dt \approx G^{-1} ∑_g (Y_i(t_g) - \hat{Y}_i(t_g))^2*

Returns a vector with the calculated MSE 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.
