coef.bamlss | R Documentation |

Methods to extract coefficients of fitted `bamlss`

objects, either coefficients
returned from optimizer functions, or samples from a sampler functions.

Method `confint.bamlss()`

produces credible intervals or parameter samples
using quantiles.

## S3 method for class 'bamlss' coef(object, model = NULL, term = NULL, FUN = NULL, parameters = NULL, pterms = TRUE, sterms = TRUE, hyper.parameters = TRUE, list = FALSE, full.names = TRUE, rescale = FALSE, ...) ## S3 method for class 'bamlss' confint(object, parm, level = 0.95, model = NULL, pterms = TRUE, sterms = FALSE, full.names = FALSE, hyper.parameters = FALSE, ...)

`object` |
An object of class |

`model` |
Character or integer. For which model should coefficients be extracted? |

`term` |
Character or integer. For which term should coefficients be extracted? |

`FUN` |
A function that is applied on the parameter samples. |

`parameters` |
If is set to |

`pterms` |
Should coefficients of parametric terms be included? |

`sterms` |
Should coefficients of smooths terms be included? |

`hyper.parameters` |
For smooth terms, should hyper parameters such as smoothing variances be included? |

`list` |
Should the returned object have a list structure for each distribution parameter? |

`full.names` |
Should full names be assigned, indicating whether a term is parametric "p" or smooth "s". |

`rescale` |
Should parameters of the linear parts be rescaled if the |

`parm` |
Character or integer. For which term should coefficients intervals be extracted? |

`level` |
The credible level which defines the lower and upper quantiles that should be computed from the samples. |

`...` |
Arguments to be passed to |

Depending on argument `list`

and the number of distributional parameters, either a
`list`

or vector/matrix of model coefficients.
