What This Document Is
These are lecture notes from STAT 710: Mathematical Statistics, taught at the University of Wisconsin-Madison by Jun Shao. The notes cover advanced topics in statistical theory, specifically focusing on the properties and behavior of sample quantiles – estimates of percentiles derived from data. This material represents a deep dive into the mathematical foundations underpinning statistical inference related to order statistics and non-parametric methods. The notes are formatted as a direct record of a lecture, complete with date and numbering.
Why This Document Matters
This resource is invaluable for graduate students in statistics, mathematics, or related fields tackling rigorous coursework in mathematical statistics. It’s particularly helpful for those seeking a detailed understanding of the theoretical properties of estimators, specifically those related to quantiles. Students preparing for advanced exams, conducting research involving non-parametric statistics, or needing a solid foundation for further study in statistical inference will find these notes exceptionally useful. They are best used in conjunction with textbook readings and problem sets to reinforce understanding.
Common Limitations or Challenges
These notes are a direct transcription of a lecture and, as such, are not a self-contained learning resource. They assume a strong prior understanding of probability theory, statistical inference, and measure-theoretic probability. The notes do not include worked examples or detailed derivations of every result; rather, they present the core concepts and theorems. Access to supplementary materials, such as a textbook and practice problems, is highly recommended for complete comprehension.
