Stefan Kloessner and Sven Wagner, "Exploring All VAR Orderings for Calculating Spillovers? Yes, We Can! A Note on Diebold and Yilmaz (2009)", Journal of Applied Econometrics, Vol. 29, No. 1, 2014, pp. 172-179. The file WeeklyVolatilities.csv contains the data which were obtained from http://ideas.repec.org/c/boc/bocode/rtz00044.html and http://www.estima.com/procs_perl/dieboldyilmaz_ej2009.zip. WeeklyVolatilities.csv was generated by opening the Excel sheets contained in the zip file and then saving the data in csv format. The data consists of time series data of estimated weekly volatilities of 19 countries' leading stock market indexes. It is organized in columns: the first column enumerates the data, the second column gives the dates, and columns 3 through 21 contain the actual data. The file SOM.r contains R code that can be used to replicate the calculations done in the paper. Notice that the last command has been turned into a comment, as executing it may take a rather long time and slow down your computer considerably. Both files are zipped in the file kw-files.zip. Since they are ASCII files in DOS format, Unix/Linux users should use "unzip -a". Stefan Kloessner S.Kloessner@mx.uni-saarland.de
