Probability and Statistics（概率论与数理统计） 下载 pdf 百度网盘 epub 免费 2025 电子书 mobi 在线

AbstractThis book is compiled based on the authors' more than ten years of experiences in teaching the course of Probability and Statistics for students from School of International Education, Wuhan University of Technology. This book covers nine chapters, i.e., Probability of Events, Random Variables and Distributions, Multivariate Random Variables, Numerical Characteristics of Random Variables, Law of Large Numbers and Central Limit Theorems, Random Samples and Sampling Distributions, Parametric Estimation, Hypotheses Testing, and Some Background Materials. Each chapter is followed by rich and typical exercises. The book should be most suitable to non-math major undergraduate students who study Probability and Statistics as the bilingual course.
