A Comparison between the Prediction of State Space models and Stochastic Dynamic Linear Systems with Application

This Paper is concerned with the synchronizing between numbers of dynamic linear system models with different parameters with their two different kinds. The first kind represented the equation error model which included ARMAX and ARX, also the second kind was the output error model which contained BJ and OE , and, another state space models, After the application of the above models on the real data ,the comparison has been done, we choose the ARX(1,7,3) and the state space model with 4 parameters which gave the minimum statistical criteria. These two models are also used in forecasting and another comparison has been done between two forecasted models, and we conclude that the forecasted dynamic linear system model is the best which gave the minimum statistical criteria.
