ci_rbod_constr_bad_Q {Compind} | R Documentation |

The Conditional robust constrained Benefit of the Doubt function introduces additional constraints to the weight variation in the optimization procedure (Constrained Virtual Weights Restriction) allowing to restrict the importance attached to a single indicator expressed in percentage terms, ranging between a lower and an upper bound (VWR); this function, furthermore, allows to calculate the composite indicator simultaneously in presence of undesirable (bad) and desirable (good) indicators allowing to impose a preference structure (ordVWR). This function, in addition to being robust against outlier data (see `ci_rbod_constr_bad`

function) allows to take into account external contextual continuous (`Q`

) or/and ordinal (`Q_ord`

) variables.

```

`x` |
A data.frame containing simple indicators. |

`indic_col` |
A numeric list indicating the positions of the simple indicators. |

`ngood` |
The number of desirable outputs; it has to be greater than 0. |

`nbad` |
The number of undesirable outputs; it has to be greater than 0. |

`low_w` |
Importance weights lower bound. |

`pref` |
The preference vector among indicators; For example if |

`M` |
The number of elements in each of the bootstrapped samples. |

`B` |
The number of bootstrap replicates. |

`Q` |
A matrix containing continuous exogenous variables. |

`Q_ord` |
A matrix containing discrete exogenous variables. |

`bandwidth` |
Multivariate mixed bandwidth for exogenous variables; it can be calculated by |

An object of class "CI". This is a list containing the following elements:

`ci_rbod_constr_bad_Q_est` |
Composite indicator estimated values. |

`ci_method` |
Method used; for this function ci_method="rbod_constr_bad_Q". |

`ci_rbod_constr_bad_Q_weights` |
Raw weights assigned to each simple indicator. |

`ci_rbod_constr_bad_Q_target` |
Indicator target values. |
