Define sequence dating

Sanctified since early times, Mt. Raven to describe the process whereby two or more species depend on the interactions between them. The scatterplot of the first two correspondence analysis axes shows the typical parabola shape. The assumption was that certain styles of pottery were popular in certain times, and during that time, the popularity would reach a peak and then fade away.

The study of the composition, texture, and structure of the minerals in the clay from which pottery is manufactured. This was one of the reasons why they proposed an adjustment which is called detrended correspondence analysis. However, the two terms are not exactly interchangeable.

With each new context

Note that external evidence is needed to establish the direction of the sequence calculated, i. With each new context a new type appears and another type disappears. In fact, the intervals of production may be somewhat longer than those calculated by the algorithm. For this regular data, it seems reasonable to assume constant time intervals for contexts adjacent in time.

The traits or attributes included in the seriation must depend on cultural aspects rather than on function. As expected, the dots indicating the occurrence of a type in a context are close to the diagonal of the table. Note that the dots are even more compact along the diagonal of the table compared to the raw data. It is still widely used today, although often in modified form.

Note that external evidence is

Jump to navigation Jump to search Sequence Dating, a relative dating method, allows assemblages to be arranged in a rough serial order, which is then taken to indicate time. Similarly, contexts containing one object only are irrelevant for seriation.
