# Where the results of the command with option use_shock_groups are stored

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.
