Traditional portfolio theory based on multivariate normal distribution assumes that investors can benefit from diversification by investing in assets with lower correlations in order to avoid risk.

基于多元正态分布的投资组合理论认为，投资者可以通过投资于低相关性的不同资产规避风险，资产间的相关性可以通过线性相关系数来度量。

The main topics are: matrix algebra, multivariate normal distribution, discrimination and classification, principle components, factor analysis, canonical correlation analysis.

本课程的主要内容包括矩阵代数、多元正态分布、判别分析、聚类分析、主成分分析、因子分析、典型相关分析。

First of all, this paper establishes the simulation method for fluctuating wind with a multivariate normal distribution model and an autoregressive filter. On the basis of simulation results of the wind field, the time dispersion of the buffeting forces by turbulent wind is achieved.

首先，本文利用多变量正态分布模型并结合线性滤波法的自回归模型建立了脉动风的仿真模拟方法，从而实现了对紊流抖振力的时间离散。

However, post-stratification requires the knowledge of multivariate joint distribution of the population when more than one post-stratifying variable is considered.

然而，调查研究需要检定的变数，通常超过一个以上，而「事后分层加权」所需之母群多变数联合分布值，往往为未知。

The sample proportion has mean and variance and (3.7) In Section 14.1.4 we show that for , and have covariance (3.8) The sample proportions have a large-sample multivariate normal distribution.

样品比例有手段和变化并且(3.7)在部分14.1.4 我们显示那为，和有协变性(3.8)样品比例有大样品多维分布的正常分配。

PCA is not only used as feature extracting method (where process variables are subjected to multivariate normal distribution), but also as a tool for dimension reduction; BSA is used to extract independent features or process blind source signals from process information in information theory sense, which is more effective than PCA in describing the process.

主元分析方法不仅作为一种过程特征的提取方法（在过程信息服从多元正态分布的情况下），而且也作为一种过程数据降维的主要工具（在过程盲源信号提取的情况下）；盲源信号分析是从信息论的角度，从过程信息中提取出尽可能独立的过程特征信号或过程原始信源信号，它具有比主元分析更好的刻画过程运行特征的性能。

The software system not only performs common process capability index computation, common distribution function computation and curve fitting, but also has the function especially for computing process capability index for non-normal distribution and multivariate.

该软件不仅包含常规工序能力指数的计算，通常遇到的分布函数的计算与拟合，而且具有非正态和多变量工序能力指数计算两个重要模块。

Simulation results show that the application of multivariate statistics method to monitor continuous casting mould process is feasible.

仿真结果表明，多变量统计方法应用于连铸结晶器过程的监测是可行的。

Diabetes is a social disease that affects several million people worldwide.
