Hi Prof. Pfeifer and to all, I have two questions. 1.The results of the command “shock\_decomposition” are stored in an array oo\_.shock\_decomposition. Where the results of the command with option use\_shock\_groups (shock\_decomposition(use\_shock\_groups=group1)) are stored? 2.When we group shocks into a groups, their action is simply summed up (shocks need to be summarized ncluding signs)? Thank you, Leonid ---

Dear Leonid, they are not stored, but just plotted. Indeed, grouping adds all contributions from shocks in the group, including signs. best Marco ---
