If period and cohort effects are taken into account (effects = TRUE) the method uses all available years and diagonals for estimation of the period and cohort effects.

`data` |
Demographic data presented as a matrix. |

`effects` |
Controls if the cohort and period effects are taken into account. |

`cornerLength` |
Sets the smallest length of a diagonal to be considered for cohort effects. |

`affdDiagonals` |
Diagonals to be used for cohort effects. The first diagonal is at the bottom left corner of the data matrix. |

`affdYears` |
Years to be used for period effects. |

`lower` |
Lowest possible values for the optimization procedure. |

`upper` |
Highest possible values for the optimization procedure. |

`init` |
Initial values for the optimization procedure. |

`reltol` |
Relative tolerance parameter to be supplied to |

`parameters` |
Optional model parameters. If not provided, they are estimated. |

`trace` |
Controls if tracing is on. |

`control` |
The control data passed directly to |

A list of four components: smooth surface, period effects, cohort effects and parameters used for smoothing (passed as a parameter or estimated).

`smoothAPC`

and `signifAutoSmoothAPC`

. The latter might give slightly better performance.
