fit_gamlss( data, age.min = 0.25, age.max = 18, age.int = 1/12, keep.models = F, dist = "BCCGo", mu.df = 4, sigma.df = 3, nu.df = 2, tau.df = 2, trans.x = F, lim.trans = c(0, 1.5), value, tmpdata )

`data` |
dataframe as return by select_meas() |

`age.min` |
lower bound of age |

`age.max` |
upper bound of age |

`age.int` |
stepwidth of the age variable |

`keep.models` |
indicator whether or not models in each iteration should be kept |

`dist` |
distribution used for the fitting process, has to be one of BCCGo, BCPEo, BCTo as they are accepted by lms() |

`mu.df` |
degree of freedem location parameter |

`sigma.df` |
degree of freedem spread parameter |

`nu.df` |
degree of freedem skewness parameter |

`tau.df` |
degree of freedem kurtosis parameter |

`trans.x` |
indicator wether age should be transformed or not |

`lim.trans` |
limits for the exponent of transformation of age |

`value` |
names of the value variable (character) if different from value, ignored |

`tmpdata` |
ignored |

wrapper around the `lms`

function in the gamlss package
returns the fitted lms-parameter at given age points
the function is called inside `do_iterations`

and may not called directly

list containing a dataframe of the fitted lms parameter at the given age points and the fitted model
