In cluster analysis the silhouette is a validation measure of how well each object fits the cluster it was assigned to: for a point it compares the mean distance to other members of its own cluster against the mean distance to the nearest neighbouring cluster, yielding a value from -1 to 1 where high means well matched and negative means probably misassigned. Rousseeuw's 1987 Silhouettes: a graphical aid to the interpretation and validation of cluster analysis introduced both the per-point coefficient and the silhouette plot, whose stacked bars give the construct its name by evoking a shape. The referent is a goodness-of-clustering score, unrelated to a backlit photograph or a garment's line and sharing only the picture-of-an-outline metaphor.[1]
