Graduate and postgraduate students in finance, economics, risk management as well as practitioners in finance and portfolio optimization will find this book beneficial.The first part, Chapters 1-10, is dedicated to the exploratory data analysis of financial assets, the second part, Chapters 11-14, to the framework of portfolio design, selection and optimization, the third part, Chapters 15-19, to the mean-variance portfolio approach, the fourth part, Chapters 20-23,.No comments for "Portfolio Optimization with R/Rmetrics".References 28 3 Financial market data.1 Stylized facts of financial market returns.1.1 Stylized facts for univariate series.1.2 Stylized facts for multivariate series.2 Implications for risk models.This edition has been extensively revised to include new topics on risk surfaces and probabilistic utility optimization as well as an extended introduction to R language.Includes updated list of R packages for enabling the reader to replicate the results in the book.This book divides roughly into five parts.
Is accompanied by a supporting website featuring examples and case studies.
It also serves well as an accompanying text in computer-lab classes and is therefore suitable for self-study.
