MATLAB概率与数理统计分析（第2版）》以概率与数理统计的基本原理为线索，以matlab为辅助条件，分别介绍了概率与数理统计概述、统计估计、假设检验、方差分析、回归分析、正交试验分析、聚类分析、判别分析和多元数据相关分析等内容，理论与实践相结合，向读者演示了matlab在数理统计中的应用。 　　("MATLAB Probability and Mathematical Statistics Analysis (2nd edition)" is based on the MATLAB r2011 a, on the basis of the 1st edition, further introduced the MATLAB probability and mathematical statistics analysis. "MATLAB Probability and Mathematical Statistics Analysis (2nd Edition)" takes the basic principles of probability and mathematical statistics as the clue, and takes MATLAB as the auxiliary condition. It respectively introduces the outline of probability and mathematical statistics, statistical estimation, hypothesis test, variance analysis, regression analysis, orthogonal test analysis, cluster analysis, discriminant analysis and multivariate data. The application of MATLAB in mathematical statistics is demonstrated to the readers by combining theory with practice.)
