摘要
介绍纵贯数据的定义并从统计方法的角度讨论纵贯数据在乒乓球技、战术分析中所能发挥的作用。纵贯数据的优点:在数据结构和提供的信息方面都更加丰富;更有效地进行因果联系的分析,使数据的描述性分析和探测性分析更加可靠;更好地对技、战术的动态变化进行分析;更好地识别和测量纯粹截面数据和时间序列数据中难以识别的信息。以乒乓球技、战术分析中应用纵贯数据的实例,阐述纵贯数据在乒乓球技、战术分析中,对于研究对象技、战术动态变化、技、战术的发展预判,以及数据的有效性方面所存在的重要意义。纵贯数据并不是完美无缺的,纵贯数据也并不能解决所有问题。因而在纵贯数据的辅助下,研究者需要对乒乓球技、战术的内在规律有深刻的理解。
This paper introduces the definition of longitudinal data,and discusses the role of longitudinal daa in table tennis technical and tactical analysis from the perspective of statistical methods discussed the role of longitudinal data.The advantages of the longitudinal data:provided rich information in terms of data structures;more effectively linked to causal analysis,or making a descriptive and exploratory analysis of data is more reliable;better to analysis the dynamic changes in player's technical and tactical using;better identify and measure purely the information,which cross-sectional data and time series data are difficult to recognize.Using the example of the application of longitudinal data in table tennis technical and tactical analysis,elaborated the significance of the longitudinal data in the fields of studying the player's dynamic changes and of the anticipation of the player's tactical skills,as well as the effectiveness of data.Longitudinal data is not perfect,it can not solve all problems.Thus with the auxiliary longitudinal data,the researchers need to have a deep understanding of the laws of table tennis skills and tactics.
