Define seriation dating

As explained above, seriation can be performed after a preliminary hierarchical clustering - this is seriation under tree constraints. Tree-based seriation is less complex to implement so it is much faster.

Tree-based seriation often yields better results than direct seriation without clustering. This is due to the fact that the seriation is complicated when there are several data gradients.

Preliminary clustering reduces the seriation degree of freedom and makes it easier to obtain a unidimensional result. If there is only one gradient in the data, then the preliminary clustering is not necessary, and it may define seriation dating hinder the seriation define seriation dating.

This is the simple case of a perfect seriation. This ideal situation hardly ever arises, however, and the use of several seriation methods is usually the best way to search for a satisfactory optimal reorganization.

Seriation is the first scientific dating method, invented by bar group lines up together in what is known as a "battleship curve", narrow at both. DEFINITION: A seriation technique, also called sequence dating, pioneered by Sir Flinders Petrie in the 19th century, in which artifacts are arranged according to‚Äč.

As nouns the difference between dating and seriation is that dating is a form of romantic courtship typically between two individuals with the aim of assessing the other's suitability as a partner in an intimate relationship or as a spouse the result of dating may at any time lead to friendship, any level of intimate relationship, marriage, or no relation while seriation is.
