This PCRA R package is a companion to the book Robust Portfolio Construction and Risk Analysis by R. Douglas Martin, Thomas K. Philips, Stoyan Stoyanov, Bernd Scherer and Kirk Li, scheduled for publication by Springer in 2025.
The paper "Robust Statistics for Portfolio Construction and Analysis" by R. Douglas Martin, Stoyan V. Stoyanov, Kirk Li and Mahmoud Shammaa, was published in 2023 by The Journal of Portfolio Management, 49 ( 9) 105 - 139. See the Paper Abstract, where JPM Subscribers can also download the paper.
The R script file RobustStatisticsForPortfoliosJPM2023.R for reproducing most
of the Figures and Tables in the above paper is available in the PCRA package at
PCRA/demo. Download that R script by going to PCRA/demo and double clicking
on the file, which then allows you to either click on the "Download raw file"
link or the "Copy raw file" link. If you have RStudio installed, the first choice
may open the file in RStudio. Otherwise you can paste the file into an empty R
script.
If you have any problems with the code, please send emails to both Doug Martin at
martinrd3d@gmail.com and Kirk Li at cocokecoli@gmail.com.
We will post responses in this README file.
