Description: PCA（主成分分析）算法被广泛应用于工程和科学研究中，本报告主要从PCA的基本结构和基本原理对其进行研究，常规的PCA算法主要采用线性算法，通过研究论证发现线性的PCA算法存在着许多不足，比如线性PCA算法不能从线性组合中把独立信号成分分离出来，主分量只由数据的二阶统计量—自相关阵确定，这种二阶统计量只能描述平稳的高斯分布等，因此必须对其进行改进，经改进后的PCA算法有非线性PCA算法、鲁棒算法等。我们通过PCA算法在直线（平面）中拟和的例子说明了PCA在工程中的应用。本例子采用的是成分分析中的次成分（方差最小的成分），通过对结果的分析，我们可以看出，利用PCA算法可以得到较好的拟和结果。-PCA (Principal Component Analysis) algorithm has been widely used in engineering and science research, This report mainly from the PCA and the basic structure of the basic tenets of its research, Conventional PCA algorithm used mainly linear algorithm, found through research and demonstration linear PCA algorithm, there are many inadequate, For example, not linear PCA algorithm from the linear combination of the independent signal components separated, PCA data only from the second-order statistics-auto-correlation matrix to determine, Such second-order statistics can only describe a smooth Gaussian distribution, it is necessary to improve it.

Description: Phase noise resulting in Common Phase Error
(CPE) and Inter-Carrier Interference (ICI) is a critical challenge
to the implementation of OFDM systems. Modeling phase noise
as a stationary Gaussian random process with the specified
power spectrum density, different from conventional approaches
which mostly relay on pilots to provide CPE estimation, we
explore the statistical characteristics of the sufficient statistics
then propose a pilot-aided decision-directed approach according
to maximum-likelihood criterion. Numerical results demonstrate
that the proposed algorithm enjoys 2dB gain at moderate SNR
and is quite robust against possible model mismatch Platform: |

Description: EM算法的详细介绍，包括EM算法的方法论、原理以及应用等
-This new edition remains the only single source to offer a complete and unified treatment of the theory, methodology, and applications of the EM algorithm. The highly applied area of statistics here outlined involves applications in regression, medical imaging, finite mixture analysis, robust statistical modeling, survival analysis, and repeated-measures designs, among other areas. The text includes newly added and updated results on convergence, and new discussion of categorical data, numerical differentiation, and variants of the EM algorithm. It also explores the relationship between the EM algorithm and the Gibbs sampler and Markov Chain Monte Carlo methods.
With plentiful pedagogical elements-chapter introductions, author and subject indices, exercises, and computer-drawn graphics-this Second Edition of The EM Algorithm and Extensions will prove an essential companion for students and practitioners of advanced statistics Platform: |

Description: 本文档的目的是为具有一定统计（数学）背景的R 软件初学者提供一个快速认识R 软件的
平台，如果你无此背景，可能会对其中的若干表达存在疑问。这篇文档重点不在统计方法上，因
此所列问题不可能详尽到统计学的每个知识点。
R 是一个很庞大的体系，在CRAN 的Task Views 上可以清楚地看到贝叶斯推断、聚类分
析、机器学习、空间统计、稳健统计等方法的介绍。而这些方法又通过相应的R Packages 扩展，
可以说学习R 是一件没有尽头的事情。
如果你的英文阅读没问题，那么精读一本关于R 的原版书籍也是一个不错的选择，但这个
开头常常让人很头痛。希望这份44 页的文档，对你认识、学习R 是个不错的帮助-The purpose of this document is to have a certain statistics (math) background beginner R software provides a quick understanding of R software platform, if you no such background, some of which might be expressed in doubt. This document focuses not on statistical methods, and therefore can not be exhaustive list of issues to each statistical knowledge. R is a very large system, in the Task Views CRAN can be clearly seen on Bayesian inference, cluster analysis, machine learning, spatial statistics, robust statistical methods such as introduction. These methods and extend through the corresponding R Packages can be said that learning R is a never-ending thing. If your English reading is no problem, then intensive one on the R' s original books is also a good choice, but the beginning is often quite confusing. We hope this 44 document, you know, learning R is a good help Platform: |
