【摘要】 为全面理解回归分析,文章采用启发式教学法,以寻找函数关系为目标,围绕回归分析"做什么(WHAT)"、"为什么做(WHY)"、"怎么做(HOW)"即"WWH"三个问题展开.教学从数据中寻找函数关系所面临的多解问题入手,剖析其产生的原因及避免方法来介绍回归分析的求解步骤,通过案例加深对回归分析的基本思想和具体应用的理解,并展现教学方法使用前后教学效果的对比.更多还原

【Abstract】 In order to comprehensively understand regression analysis, this paper adopts heuristic teaching methods, aiming at finding the functional relationship, focusing on three questions of regression analysis: what to do(WHAT), why to do(WHY), and how to do(HOW), namely "WWWH". Starting with the multi-solution problem of finding function relations in data, this paper analyses its causes and avoidance methods, introduces the solving steps of regression analysis, deepens the understanding of the basic idea and specific application of regression analysis through cases, and shows the comparison of teaching effects before and after the use of teaching methods.更多还原
