overridevirtual 
Callback to set stat parameters.
This callback is typically used for complex stats (e.g., distributions) that need parameters in addition to a name and a description. Stat names and descriptions should typically be set from the constructor usingo from the constructor using the ADD_STAT macro.
Reimplemented from gem5::statistics::Group.
