According to concept 9, concept 10 and concept 3, we can then conclude that we have a stationary series. After the data series is stationary, we can then determine the ARMA model parameters. The T rations of the estimate coefficient are significant. In addition to storing model building knowledge, concepts in the KB provide several important functions. This includes information such as KB names, number of attributes in each KB, name of each attribute, and attribute type.
Concepts serve as control points.
We can use certain concepts to determine the type of processing to be taken place. Each concept has the actual value or information of each attribute in the concept. Depending on the value status of an attribute, we may associate it with different types of processing, either with a procedure or associate it with a process. Concepts serve as points of integration. Information from statistical computation procedures or other devices can be integrated or monitored by each concept to constantly adjust the data series or the descriptive model until reaching an optimal or satisfactory result.
