Abstract

          In this research, the transfer function models were diagnosed based on seasonal data represented by solar brightness as inputs and temperatures as outputs, where a double seasonal model was obtained which was used in diagnosing the transfer function models as well as diagnosing the output error models represented by the (OE) model and the (BJ) model and compared the results. Finding that the dynamic systems give a better diagnosis than the transfer function models, depending on some statistical criteria
