从典型相关分析洞悉我国粮食综合生产能力 总被引:4,自引:0,他引:4
在全球粮食危机的背景下,笔者试图对我国粮食综合生产能力进行解剖洞悉。将粮食综合生产能力分解为土地产出能力、劳动产出能力和资本产出能力3项形成"产出组",同时围绕土地、劳动、资本、技术、制度五大要素,利用可以直接量化和间接量化的13项指标形成"影响因素组",利用13个粮食主产区2000-2006年的数据,采取典型相关分析方法对两组指标进行分析,结果显示土地产出能力和劳动产出能力相对比较突出,而资本产出能力却有待发掘;对粮食综合生产能力最具影响力的因素是人均耕地、劳动力受教育情况,最不具影响力的因素是金融资源支持度。 相似文献

为了贯彻德,智,体全面发展的教育方针,国家教委1990年向全国各高校颁发了《大学生体育合格标准》.影响大学生体育达标等级的因素有很多,主要分成身体形态指标,机能指标和运动素质指标三大类.对这些指标中的因素进行分析,找出各指标之间的关系,确定相对重要的因素,这对高校体育教师与学生在教学与平日锻炼中具有一定的指导作用.本文运用典型相关分析方法,分析了大学生身体形态指标与运动素质指标之间的相关关系.我们从华东地质学院95级625名学生的体育达标成绩中,随机抽取男,女各302人,每人七项指标,运用典型相关分析方法,… 相似文献

In this paper, a novel supervised dimensionality reduction method is developed based on both the correlation analysis and the idea of large margin learning. The method aims to maximize the minimal correlation between each dimensionality-reduced instance and its class label, thus named as large correlation analysis (LCA). Unlike most existing correlation analysis methods such as CCA, CCAs and CDA, which all maximize the total or ensemble correlation over all training instances, LCA devotes to maximizing the individual correlations between given instances and its associated labels and is established by solving a relaxed quadratic programming with box-constraints. Experimental results on real-world datasets from both UCI and USPS show its effectiveness compared to the existing canonical correlation analysis methods. 相似文献

系统综述了自19世纪开始且至今常用统计相关性的方法,例如Pearson和Spearman相关系数,CorGc和CovGc 相关性及距离相关性方法。重点介绍了2011年提出的MIC方法以及由此引发的毁誉参半的大量评述,旨在揭示这一热点领域研究面貌。该领域不仅受到统计学家的关注,而且受到了分析大样本和异质数据的应用研究领域的学者们的追捧,例如基因组生物学家和网络信息研究者。这些研究者期望在众多已有方法的理解和剖析中更恰当地付诸应用,并提出新的应用问题来推动新的分析方法的创造。 相似文献

Regularized generalized canonical correlation analysis for multiblock or multigroup data analysis 总被引:1,自引:0,他引:1
This paper presents an overview of methods for the analysis of data structured in blocks of variables or in groups of individuals. More specifically, regularized generalized canonical correlation analysis (RGCCA), which is a unifying approach for multiblock data analysis, is extended to be also a unifying tool for multigroup data analysis. The versatility and usefulness of our approach is illustrated on two real datasets. 相似文献

Canonical correlation analysis based on information theory 总被引:2,自引:0,他引:2
In this article, we propose a new canonical correlation method based on information theory. This method examines potential nonlinear relationships between p×1 vector Y-set and q×1 vector X-set. It finds canonical coefficient vectors a and b by maximizing a more general measure, the mutual information, between aTX and bTY. We use a permutation test to determine the pairs of the new canonical correlation variates, which requires no specific distributions for X and Y as long as one can estimate the densities of aTX and bTY nonparametrically. Examples illustrating the new method are presented. 相似文献

We consider stationary Poisson line processes in the Euclidean plane and analyze properties of Voronoi tessellations induced
by Poisson point processes on these lines. In particular, we describe and test an algorithm for the simulation of typical
cells of this class of Cox–Voronoi tessellations. Using random testing, we validate our algorithm by comparing theoretical
values of functionals of the zero cell to simulated values obtained by our algorithm. Finally, we analyze geometric properties
of the typical Cox–Voronoi cell and compare them to properties of the typical cell of other well-known classes of tessellations,
especially Poisson–Voronoi tessellations. Our results can be applied to stochastic–geometric modelling of networks in telecommunication
and life sciences, for example. The lines can then represent roads in urban road systems, blood arteries or filament structures
in biological tissues or cells, while the points can be locations of telecommunication equipment or vesicles, respectively. 相似文献

Let Σ be an n × n positive definite matrix with eigenvalues λ1 ≥ λ2 ≥ … ≥ λn > 0 and let M = {x, y | x?Rn, y?Rn, x ≠ 0, y ≠ 0, x′y = 0}. Then for x, y in M, we have that and the inequality is sharp. If is a partitioning of Σ, let θ1 be the largest canonical correlation coefficient. The above result yields . 相似文献

We study convergence behavior of discrete martingales with values in the interval [0,1] from a measure theoretical point of view as well as from a topological one. We show that almost all martingales converge to 0 or 1 almost everywhere. On the other hand, a typical martingale diverges on a comeager set. 相似文献
