**XYOM ANALYZES, CLASSIFICATION **

**Input:**

A single file containing data which may be:

- Global size (one column matrix)
- DISTANCES (square matrix),
- Mahalanobis distances (i.e., Euclidean distances between …_DF.txt)
- Euclidean distances between …_PC.txt

- PRINCIPAL COMPONENTS (rectangular matrix)
- TABLE (rectangular matrix)
- matrix of traditional measurements, matrix of …_NEF,matrix of …_ORP, etc…)

**Analyses:**

- if input data are labelled as
**TABLE****PCA****(Principal Component Analysis**)

- if input data are labelled as
**PC****DA**(**Discriminant analysis**), a DA always assumes the entry data are PC; it cuts the sequence of PC to the number of individuals in the smallest group, minus one.- Validated classification based on
**Maximum likelihood method**(**CCCMLi**) - Validated classification based on
**Mahalanobis distance method**(**CCCMaha**) **HC****BOOTSTRAP**(**hierarchical clustering**): single linkage algorithm, bootstraps of input data and resulting trees (See Couette et al,…)

- if input data are labelled as
**DISTANCES (Mahalanobis, Euclidean)****HC**(**hierarchical clustering**): single linkage algorithm

- if input data are labelled as
