We are hugely grateful to the Editors, Methodologists and members of the Scientific Committee without whom the Academic Journal Guide 2015 would not be possible.The work they have carried out to analyse data, consult with subject communities and find consensus has led to an impressive and robust Guide to the range, subject matter and quality of journals in which
business and management academics publish their research. With their hard work we have a Guide which is genuinely based upon peer review, along with editorial and expert judgements following from the evaluation of many hundreds
of publications.

本书是一本面向商业数据分析初学者的教材，从具体的商业数据分析案例入手，使读者掌握数据挖掘的目的、理念、思路与分析步骤。本书力图淡化技术，对于方法的介绍也尽量避免涉及过多的数学内容，和高等数学相关的内容只在线形回归和主成分分析这两节中涉及，而且都辅以图形做形象的展现。因此本书的读者只需要具有高中水平的数学基础即可。但是本书强调每种方法的假设、适用条件都与商业数据分析的主题匹配。在教学实践中，我们发现业务经验丰富和有较好商业模式理解的学员，在学习数据挖掘时有更好的效果，主要原因可能是这类学员有较强的思辨能力、分析能力、学习目的性和质量意识，而不是简单地模仿和套用数学公式。
