一种指标异动的溯源及预测方法、装置
摘要：
本申请提供了一种的指标异动的溯源及预测方法、装置，均已预先建立的Granger图模型为搜索基础，因为Granger图模型中的每一节点均对应一个指标，任意一条存在于两个节点之间的边用于表示这两个节点间的因果关系，所述边由原因节点指向结果节点，所以通过此模型可以展现出指标间的因果关系，所以，在已知指标异动的情况下，即可通过发生异动的指标对应的节点，向此节点原因节点的方向进行溯源，从而查询出指标异动的原因，以及，向此节点结果节点的方向进行预测，从而预测出可能异动的指标。
摘要（英）：

The invention provides an index change traceability and prediction method and an apparatus. A Granger graph model established in advance is taken as a searching base. Each node in the Granger graph model corresponds to one index and any one edge between the two nodes is used for expressing a causal relationship of the two nodes. The edge points to a result node from a reason node. Through the model, the causal relationship between indexes can be presented. Under the condition that an index change is known, through the node corresponding to the changed index, traceability is performed on a direction of the reason node of the node so that a reason that the index changes is inquired. And prediction is performed on a direction of the result node of the node so as to predict the index which may change.
