The six sigma black belt will understand the difference between regression and correlation studies 译文:六西格玛黑带能理解回归和相关性研究的差异。
In this paper, the introduction to regression and correlation is simplied by using standardized variables, therefore its model and meaning become intuitive and comprehensible 摘要用标准化变量方法,对线性回归模型的描述进行了简化,使其统计模型得直观和容易理解。
Statistical inference techniques will be considered such as estimates and their accuracy, tests of means, proportions and other characteristics, regression and correlation and an introduction to the analysis of counted data 统计推论技术会考虑到如评价和它的准确性、方法检验、比例和其它特征、衰退与相关性和数量数据分析的基础。
Chapter two, we described the income disparity objectively and carried on the analysis of different stages . chapter three, we made comparative analysis of the income disparity between urban and rural residents among provinces by using linear regression and correlation analysis from the view of spatial distribution and time series . as to the reasons that made the synchronous and asynchronous income disparity change between provinces and whole country, we also made elementary analysis 第三章,对各省城乡居民收入差距进行了省区间比较的实证分析,采用了回归分析和相关性分析的方法,从空间分布和时间序列变化两个方面对省区间的城乡居民收入差距进行了初步研究,揭示了城乡居民收入差距在空间布局以及时间序列变化上的不同步性;同时,还对形成这种空间不平衡和时间变化不同步的原因进行了初步探讨。
Abstract : events contributing to the establishment of statistics the science of data and its chemical branch are epitomized . as the new chemical branch named chemometrics or chemstatistics has been disputed in the circles of chemistry for a long time, reasons for adopting chemstatistics are given, which is defined as the science of gathering or generating, describing, summarizing and interpreting the data concerned to acquire new chemical knowledge or information . the fact that many traditional statistical methods, such as significance tests, analysis of variance, regression and correlation, and some others not usually considered statistical, such as model building, monte carlo method, fourier transformation, artificial nerval networks and pattern recognition, each contains one or more of the five connotations of statistics is expounded . the regular pattern that a chemstatistician grows up is approached . the urgent task is to include chemstatistics in the undergraduate or graduate curriculum of chemistry specialty . the goal of the project is to nurture chemists who know statistics 文摘:本文追溯了统计学发展、建立中的大事,陈述了它的定义及其化学分支发展、建立的梗概;鉴于化学界对该新兴化学分支学科的名称长期存在争议,提出了以化学统计学而不以化学计量学为该学科名称的理由,把化学统计学定义为一个研究有关数据的收集或产生、描述、分析、综合和解释,以获得新化学知识或信息的学科;阐明了许多公认属于统计学的方法,如显著性检验、方差分析、回归和相关,以及一些尚未认定属于统计学的方法,如模型建立、蒙特卡罗方法、傅立叶变换和人工神经网络,都含有统计学5个内涵中的一个或多个;探讨了化学统计学家成长的模式,认为当务之急是把化学统计学纳入化学专业的教学计划,以培养懂统计学的化学家。
