The problem is that if I extend it to "by group1 group2 : egen var1new = neutralize (var1 var2 var3)" or "by group1 group2, sort : egen var1new = neutralize (var1 var2 var3)" etc., then the code does not work as it depends upon levelsof to loop.
egen groupgroup = group(group1 group2)
by groupgroup : neutralize(<whatever>)
