getBestPamsamMO | R Documentation |

The HIPAM algorithm starts with one large cluster and, at each level, a given (parent) cluster is partitioned using PAM.

In this version of HIPAM, called $HIPAM_MO$, the number k of (child) clusters is obtained by maximizing the silhouette width (asw). See Vinue et al. (2014) for more details.

The foundation and performance of the HIPAM algorithm is explained in `hipamAnthropom`

.

getBestPamsamMO(data,maxsplit,orness=0.7,type,ah,verbose,...)

`data` |
Data to be clustered. |

`maxsplit` |
The maximum number of clusters that any cluster can be divided when searching for the best clustering. |

`orness` |
Quantity to measure the degree to which the aggregation is like a min or max operation. See |

`type` |
Option 'MO' for using $HIPAM_MO$. |

`ah` |
Constants that define the |

`verbose` |
Boolean variable (TRUE or FALSE) to indicate whether to report information on progress. |

`...` |
Other arguments that may be supplied. |

A list with the following elements:

*medoids*: The cluster medoids.

*clustering*: The clustering partition obtained.

*asw*: The asw of the clustering.

*num.of.clusters*: Number of clusters in the final clustering.

*info*: List that informs about the progress of the clustering algorithm.

*profiles*: List that contains the asw and sesw (stardard error of the silhouette widths) profiles at each
stage of the search.

*metric*: Dissimilarity used (called 'McCulloch' because the dissimilarity function used is that explained in McCulloch et al. (1998)).

This function belongs to the $HIPAM_MO$ algorithm and it is not solely used. That is why there is no section of *examples* in this help page. See `hipamAnthropom`
