The selection of weight factor λ in engineering calculation and on-line control still lacks a reasonable and accurate method. The authors establish a regression model for λ on the basis of a statistical analysis of data log observed in the Corporation's shop practice. The authors maintain that the independent variable and the model he resort to are justiliable. The weight factor model not only gives an accuracy as good as its prototype but cuts down by 50% the time spent on pressure forecast...

A factor analysis using average correlation matrices of threestandardized age groups in four sample-sizes such as the urban and ruralresidets of WAIS-RC, WAIS and WAIS-R, were performed usingprincipal component analysis method. Main results are as follows: 1. Number of factors: In most age groups of the four sample sizesonly one principal factor was found, while the other age groups hadtwo principal factors. 2. Results of two different factor analytic methods: In general, allverbal subtests had higher loading on factor A, while all performancescale subtests except digit symbol had higher loading on factor B. 3. Results of the three different factor analytic methods: the highestloading on factor A is found in the following subtests: information,comprehension, similarities and vocabulary Medium loading is foundin picture completion. The highest loading on factor B is found in objectassembly, medium loading in picture completion, block design andpicture arrangment; the highest loading on factor C is found in digitspan, medium loading in arithmetic and digit symbol. 4. Results of analysis of g factor: Some subtests such as information,similarities, comprehension, vocabulary, block design and picturecompletion have the highest loading on g factor, other subtests of fullscale have a medium loading. 5. Factor models between WAIS-RC and WAIS of WAIS-R arevery similar.

本文用主成分分析法对韦氏成人智力量表中国修订本(WAIS-RC)的城市与农村两个常模以及WAIS和WAIS-R进行因素分析,发现这三套测验都负荷较高的g因子;常识,领悟,相似性和词汇测验负荷较高的A(言语理解)因子,填图,木块图,图片排列和物体拼凑测验负荷较高的B(知觉组织)因子,而数字广度,算术和数字符号测验负荷较高的C(记忆/集中注意)因子。因子模型是极相似的,这说明WAIS-RC具有较好的结构效度,保持了原量表的功能。同时,所建立的因子模型也为使用者在使用测验和分析解释结果时提供了有用的参考资料。

Most of the current procedures for multiple factor analysis are concerned with complete observations, and to obtain MLE by the ordinary Flettcher-Powell method or Newton-Raphson method. From the practical point of view, however, usual observations contain missing values and occasionally restriction exist among parameters in multiple factor model. The present paper is to propose a systematic procedure to obtain the maximum likelihood estimation (MLE) under the general necessity described above. The procedure is fundamentally based on Dempster-Laird-Rubin's EM algorithm, and gives an excellent property to obtain iteratively and surely the MLE with monotonous approach from initial values.

本文将EM方法应用于含有欠测数据的因子分析的最大似然估计问题,利用EM法统一处理了为保证估计唯一性的种种条件下的最大似然估计问题,得到了相当统一的迭代算法。这种处理方法可以简单地将根据欠测样本估计正态分布的期望向量与协方差阵的问题及回归问题作为其特例。从而使建立具有泛用性的计算程序成为可能。
