so lets say we have list 1 1 1 2 2 3 Then the 1st mode =1 2nd most freq obs = 2nd mode = 2 3rd mode = 3. Please note I have no formal training in statistics so I may be wrong but I think this is what it means. so I would say egen j=mode(list),numode(2) to populate j with the 2nd mode ie. 2 in this case. so how would I do this ? Which summary statistic refers to the mode. And I am still puzzled as to why someone would not allow us to set local j=max(list) cos that seems intuitive. Thank you, Ashim.
