A Case Study on application of data mining method in cross-selling of retail banking

交叉销售是一种以企业与客户的现有关系为基础去销售另一个产品的营销战略，通过交叉销售，商业银行不仅能够对现有客户扩大销售来增加利润，还能增强客户粘性以支撑未来可持续发展。但国内商业银行在零售客户交叉销售活动组织开展方面，仍然较为严重地依赖业务经验，而非数据挖掘模型。因此，存在交叉销售决策难、效率低、成本高等问题。通过数据挖掘方法的应用，能够促进商业银行零售客户交叉销售决策科学化、目标精准化和组织自动化，从而达到提升效率、降低成本和扩大成果的目的。 本文以实证性研究为主，研究的逻辑是：从某商业银行零售客户真实数据这一案例出发，利用IBMSPSSModeler挖掘工具，根据CRISP-DM(Cro...Cross selling is a kind of marketing strategy to sell another product basing on the foundation of customer relationship, through cross saling, commercial banks can not only to increase profits from existing customers, but also can enhance the customer viscous to support sustainable development in the future.

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
