Many macroeconomic time series exhibit non-stationary behaviour. When modelling such series an important problem is to assess the nature of this non-stationary behaviour. Initial interest centred on two types of linear non-stationary models, namely those for which the removal of a trend induces stationarity and those for which taking the first difference produces a stationary series. The latter are referred to as unit root models. More recently, other models such as state…

The analysis is based on a data-generating model, which takes careful account of the various kinds of uncertainty involved in relating observed radiocarbon dates of artifacts to successive chronological beginning and ending dates of significant archaeological phases. In addition to its intrinsic interest as a possible model for many kinds of archaeological data of this type, the model poses some challenging…
