The six sigma black belt will understand the difference between regression and correlation studies 譯文:六西格瑪黑帶能理解回歸和相關(guān)性研究的差異。
In this paper, the introduction to regression and correlation is simplied by using standardized variables, therefore its model and meaning become intuitive and comprehensible 摘要用標(biāo)準(zhǔn)化變量方法,對(duì)線性回歸模型的描述進(jìn)行了簡(jiǎn)化,使其統(tǒng)計(jì)模型得直觀和容易理解。
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 統(tǒng)計(jì)推論技術(shù)會(huì)考慮到如評(píng)價(jià)和它的準(zhǔn)確性、方法檢驗(yàn)、比例和其它特征、衰退與相關(guān)性和數(shù)量數(shù)據(jù)分析的基礎(chǔ)。
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,對(duì)各省城鄉(xiāng)居民收入差距進(jìn)行了省區(qū)間比較的實(shí)證分析,采用了回歸分析和相關(guān)性分析的方法,從空間分布和時(shí)間序列變化兩個(gè)方面對(duì)省區(qū)間的城鄉(xiāng)居民收入差距進(jìn)行了初步研究,揭示了城鄉(xiāng)居民收入差距在空間布局以及時(shí)間序列變化上的不同步性;同時(shí),還對(duì)形成這種空間不平衡和時(shí)間變化不同步的原因進(jìn)行了初步探討。
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:本文追溯了統(tǒng)計(jì)學(xué)發(fā)展、建立中的大事,陳述了它的定義及其化學(xué)分支發(fā)展、建立的梗概;鑒于化學(xué)界對(duì)該新興化學(xué)分支學(xué)科的名稱長(zhǎng)期存在爭(zhēng)議,提出了以化學(xué)統(tǒng)計(jì)學(xué)而不以化學(xué)計(jì)量學(xué)為該學(xué)科名稱的理由,把化學(xué)統(tǒng)計(jì)學(xué)定義為一個(gè)研究有關(guān)數(shù)據(jù)的收集或產(chǎn)生、描述、分析、綜合和解釋,以獲得新化學(xué)知識(shí)或信息的學(xué)科;闡明了許多公認(rèn)屬于統(tǒng)計(jì)學(xué)的方法,如顯著性檢驗(yàn)、方差分析、回歸和相關(guān),以及一些尚未認(rèn)定屬于統(tǒng)計(jì)學(xué)的方法,如模型建立、蒙特卡羅方法、傅立葉變換和人工神經(jīng)網(wǎng)絡(luò),都含有統(tǒng)計(jì)學(xué)5個(gè)內(nèi)涵中的一個(gè)或多個(gè);探討了化學(xué)統(tǒng)計(jì)學(xué)家成長(zhǎng)的模式,認(rèn)為當(dāng)務(wù)之急是把化學(xué)統(tǒng)計(jì)學(xué)納入化學(xué)專業(yè)的教學(xué)計(jì)劃,以培養(yǎng)懂統(tǒng)計(jì)學(xué)的化學(xué)家。
