统计数据分析

Abstract〕similar to regression analysis,cluster analysis,etc.,correlation analysis is also the basic work for information researches.canonical correlation analysis can be used to analyze the relationship between two groups of variables,and thus worth for using in information science.method of canonical correlation analysis was presented in present study.a java-based network algorithm of canonical correlation analysis was developed,which can be used to calculate the canonical correlation coefficients,canonical variable pairs,and statistical significance of canonical correlation coefficients.the algorithm may be run on java-compatible web browser.at the same time,paper publishing information and citation statistics in information science of china in past years were analyzed using the algorithm,and a number of conclusions were drawn.

摘 要〕与因果分析等一样，相关分析也是信息资料分析的基本工作。典范相关分析用于分析两组变量之间的关系，在情报信息的相关性分析方面有潜在的应用价值。本研究介绍了典范相关分析方法，给出了典范相关分析的java网络算法软件，可用于计算典范相关系数，典范变量对，以及典范相关系数的统计显著性。该软件可在兼容java的网络浏览器上运行。同时，用该算法对国内情报信息论文的发文和引文统计数据进行了分析，得到了一些结论。

Methods 45 depressed patients were enrolled as study group, which were assessed at baseline and after SSRIs therapy 8 weeks. contingent negative variation of ERPs and Wechsler memory scale as well as Wechsler adult intelligence scale were measured in all subjects, meanwhile 30 normal persons matched as control group. All the data were analyzed with SPSS software package.

In this paper, total logistics amounts are chosen as evaluation index, and artificial time series are designed to solve the shortness of statistical data in Chinese logistics. Spectrum estimation theory depicts time characteristics in frequency domain thus has such benefit than time domain methods. This paper evaluates the period of Chinese logistics using spectrum estimation. Stationarity of artificial series is verified, parameter sensitivity of truncation point is analyzed, six periods with different delay window are compared, and significance of period evaluated is tested.

中国物流统计数据缺乏，客观上限制了对其周期规律的研究，本文选取社会物流总额作为测度指标，设计了一种人工序列，解决了统计数据过短问题；谱估计法从频域角度揭示客观事物的时间特性，在研究时间序列周期波动方面具有时域分析法所不具备的优势，作者采用谱估计法对中国物流发展周期进行测定，检验了指标序列平稳性，分析了截断点参数灵敏度，比较了6种不同滞后窗下周期值，并检验了所测得周期的显著性。

From the statistical data analysis, real estate in the first quarter of this year's investment growth rate as high as 41.1 percent, slightly lower than the 43% investment in fixed assets increases, while the experience of about half a year of control, solid cast in the August an increase of 26.2 percent, while real estate investment during the first 8 months the average is still 28.8%, indicating the need to increase the real estate industry is still quite the consolidation efforts, otherwise they will be a waste of limited land resources, and in many aspects negative effects:(1) urban land supply is relatively limited, and particularly in coastal cities for the likelihood, the land and property prices in speculations will be driven by continuing higher, so that industrial and commercial service industries and residential property prices and rental values of retail trend or, an increase investor, home-owners or hirers of the burden of adverse business, and they may even like Hong Kong after a number of years due to land and property prices and rents are too expensive to make industrial and commercial operation of the service industry high cost, and even so that the quality of life for the people affected by high land prices and property prices have a lower erosion.

从统计数据分析，房地产在今年第一季度的投资增长速度高达百分之41.1 ，稍低于43 ％，固定资产投资增加，而经验约半年的控制，固投在8月增加了26.2点，房地产投资在头8个月的平均水平仍然是28.8 ％，表明有必要增加房地产业仍然相当巩固的努力，否则将会浪费有限的土地资源，而且在许多方面的负面影响：（ 1 ）城市土地供应相对有限，特别是在沿海城市的可能性，土地和房地产价格在投机的推动下将继续走高，因此，工业和商业服务行业及住宅物业价格和租金价值的零售趋势，或增加投资，以家庭为业主或租户的负担，不利的业务，他们甚至可能会像香港一样若干年后，由于土地和物业价格及租金过于昂贵，使工业和商业运作的服务行业成本高，甚至，这样的生活质量受影响的人高地价楼价较低侵蚀。
