Description Usage Arguments Value Examples

This function computes various weighted sum-of-squares criteria for a given partition of a dataset described by numerical features.

1 | ```
weightedss(X, cl, w = NULL)
``` |

`X` |
a matrice or a dataframe of size |

`cl` |
a vector of integers of length |

`w` |
a numerical vector of length |

`bss.per.feature` |
a numerical vector of length |

`wss.per.feature` |
a numerical vector of length |

`bss.per.cluster` |
a numerical vector of length |

`wss.per.cluster` |
a numerical vector of length |

`bss` |
a scalar representing the weighted between sum-of-squares of the partition.
It may be computed as the sum over |

`wss` |
a scalar representing the weighted within sum-of-squares of the partition.
It may be computed as the sum over |
