Hello, I am pleased to announce the initial version of tawny, a portfolio optimization package in R. Tawny is an R package for studying various correlation matrix filtering methods applied to asset returns. The filtering techniques included in the package are random matrix theory and shrinkage estimation. In addition to the filtering methods, also included in the package is a simple portfolio optimizer and functions to measure the effectiveness of the methods, including an implementation of the Kullback-Leibler divergence function. More information, code samples, and images can be found at: https://nurometic.com/quantitative-finance/tawny The code should be available on CRAN in a while, but in the mean time it is possible to download it directly via the link above. To run tawny, you will also need to install a utility package that tawny depends on: https://nurometic.com/quantitative-finance/futile Pending availability on CRAN, you can download it from the above link. Both packages are licensed GPL-2. Comments and questions are welcome. Regards, Brian Lee Yung Rowe
