Books and Proceedings

The biggest feature of the textbook "Applied Multivariate Statistical Analysis" by Professor Hadler and Professor Simma is the perfect combination of statistical theory and application. The book provides a large number of cases in the fields of finance and economics to illustrate relevant statistics. Quantitative theory, and readers can download the corresponding MATLAB or R language program to reproduce all the examples and graphics in the book, which is very helpful for readers to quickly understand and flexibly use high-dimensional data statistical analysis methods in practice. .
