ABSTRACT
Having summarized the properties of Fisher-Skellam models of population expansion, we now return to the conditions for their archaeological detection. Validating modelling results with experimental field data can often prove difficult. In situations where experiments can be reproduced, it is easy to obtain the data required to validate or invalidate the models. By contrast, in situations where experiments are difficult or impossible to reproduce, we are restricted by the available data. These restrictions may rule out modelling completely, if the available control data are too poor to make this worthwhile, or they may simply restrict the range of modelling parameters that can be used to validate the models.
