- In this article , the concept of statistical template based on data was firstly brought forward , which can effectively simulate the entire statistical computation process by recording the information of data structure and analytic method . we make the statistical template as theoretical basis of statistical analysis platform ( sap ) the statistical template can make our sap has the properties described as follow : 1 . good facility the requirement is to have the statistical knowledge , user need n ' t has any background of computer science and computational mathematics ; the time that is used to learn is short
本文通过对一般统计计算过程的分析，提出了以统计数据为中心的统计分析模板的概念，该概念以统计字段来描述统计数据的数据结构，通过记录统计数据结构信息及其相应的统计分析计算服务信息的形式在逻辑上有效地模拟了统计计算的全过程，从而为统计软件平台构建了一个坚实的理论基础，使该统计软件平台具备了以下特点： 1 、易于使用概念清晰、使用简便，作分析工作时使用者无需任何计算机科学和计算数学背景知识，懂得基本操作即可，学习周期短。 - This study was based on zimmerman ' s theory on self - regulated learning , examined the correlation between motivation and the other three components ( strategy , volition , environment ) , the role that the motivational factors played and the characteristics that the motivational factors reflected on students in self - regulated english learning at secondary vocational school . the data was collected through survey questionnaire with 5 - point likert scale and computerized by spss . correlational and descriptive statistics were used as the basis on which to produce the research questions
本研究采取定量和定性相结合的研究方法，对河南省焦作市三所中等职业学校不同年级、不同专业的五百名学生进行了问卷调查，共收到有效答卷四百九十份，并运用spss软件对调查数据进行了相关和描述统计，结果发现：在中等职业学校学生的英语自主学习中，动机因素和自主学习中的其它三个因素(学习策略、意志、环境)呈强烈正相关，而且动机因素在各因素中起着更为重要的作用。 - The indicators system involes seven subsystems , economical level 、 population and employment 、 resources and environment 、 technology and education 、 culture and health , quality of life , social security and safeguard subsystem . then took globle principal component analysis , composite index analysis and clustering analysis as tools in empirical study . this aimed at enriching the content of the comprehensive evaluation indicators system of the social development level ; made it porttay that the social development level of sichuan
社会发展水平研究方法,本文采用描述统计法、加权指数法、全局主成分分析方法和聚类分析方法相结合的方法。本文的资料来源于四川省统计局的抽样调查,选取了四川省1999 ? 2004年社会发展水平数据、四川省各市州2003年、 2004年两年的社会发展水平数据。 - And use relative fitting error to measure statistical data non - uniform error ; then introduce the method systematically of using the fuzzy comprehensive evaluation method to carry on the overall superior test of the government statistical data quality . includes the establishment of step level appraisal target system , target weight determination , calculates the factor weight in various levels , uniform test of judgment matrix , and built up the final fuzzy comprehensive evaluation model of the government statistical data quality according to the above - mentioned standard ; finally selects the partial main social economy total quantity target from chinese statistics yearbook 2003 to carry on the real diagnosis analysis : ( 1 ) confirm these social economy total quantity targets using the description statistics and the k - s inspection method to obey the lognormal normal distribution . ( 2 ) according to the two levels of inspection methods which this article proposed to carry on accuracy and the overall superior test for these social economy total quantity targets
本文首先从统计数据及质量的涵义出发,全面系统的介绍了统计数据质量的概念;其次,从研究统计数据的分布规律入手,对统计数据准确性检验问题进行了探讨,利用对数正态分布检验对反映研究对象规模大小的统计数据的质量及异常数据进行定量检查和识别,并利用相对拟合误差计量统计数据的非一致性误差;接着系统介绍了利用模糊综合评价方法对政府统计数据质量进行整体优度检验的思路,具体包括建立递阶层次的评价指标体系,指标权重的确定,计算各层次中因素的权重,判断矩阵的一致性检验,并根据上述标准建立了最终的政府统计数据质量模糊综合评价模型;然后通过从2003年中国统计年鉴资料中选取部分主要的社会经济总量指标进行实证分析: ( 1 )利用描述统计和k - s检验法来验证这些社会经济总量指标服从对数正态分布的规律; ( 2 )按照本文提出的二级检验法来对这些社会经济总量指标进行准确性和整体优度检验,从而达到综合评价政府统计数据质量的目的;最后对这种二级检验法的优点和不足进行小结,提出今后应该努力改进的方向。 - On the basis of the study of the theory and appraise method on land use in the small towns from home and abroad , this paper at first conducts a deep study on the development and role of the small towns , indicating that its development has sawn an uneven development phrase and becomes a carrier of the enterprises , a pool of surplus laborers , a hub of material exchanges between the rural and urban areas , a base of spiritual civilization , an important way to achieve urbanization . second , it conducts a study on the situation and features and the problems the land use , indicating that the efficiency of the land use is low , which has a direct influence on the development of agriculture and the role of the small towns . and the study of the demand of the land indicates the shortage of land is serious , and the small town must rationally use the land and increases its intensive role and the economical efficiency to meet the demand
在分析国内外已有关于小城镇土地利用的理论与评价方法的基础上，首先对小城镇在我国的发展、地位和作用进行了深入的分析，判明我国小城镇发展经历了一个曲折向上的发展阶段，已成为乡镇企业的载体，农村剩余劳动力的蓄水池，城乡物资交流的枢纽，农村精神文明的基地，是我国城市化的重要途径；其次，对小城镇土地资源利用现状和特征进行了探讨，并对发展小城镇建设导致的土地利用问题进行了剖析，表明目前我国大多数小城镇土地效益和规模效益低下，占用耕地过多，直接影响农业的发展，影响小城镇的地位和作用；通过小城镇土地供需分析研究表明，我国土地短缺十分严峻，小城镇土地需求缺口较大，小城镇必须合理利用现有土地，增强集约功能和土地经济效益，从而缓解需求压力；最后，论文通过运用特尔菲法，描述统计分析法、多元统计分析（主成分分析）法和系统分析法中的层次分析法（ ahp ）等一系列方法，结合定性和定量两方面，从土地质量、土地资源数量与结构、土地经济效益、环境效益、社会效益等五个方面进行分析，筛选、建立了土地资源利用评价指标体系，在因子评价的基础上，建立了土地利用综合评价模型，并给出了评价过程和方法。
