| Abstract: | An alternative way of analysing the data of tractors in Spain is presented. The dynamic Bayesian methodology leads to an adaptive procedure which enables calculation of parameter estimates, prediction and implementation of many additional features. This is easily achieved within the context of the method. Simple models were used and results show the improvement obtained. The key element is the recognition that dynamic models are essential to the study of time series data. The use of the logistic curve to model the purchase of goods in a population is well known in the literature. Despite their non-linear behaviour, approximation techniques efficiently simplify the computations. |
