Proximity Measures

Proximities are measures where similarity is expressed in terms of a metric distance function d(i, j). Different distance functions are available for interval-scaled, boolean, categorical, ordinal and ratio variables. If a dataset contains measures on multiple characteristics for multiple individuals then a matrix of proximities can be obtained across individuals using the various measures, or across measures using the individuals.

examine similarity matrix - look for minimum neighbour, cluster analysis, etc.
