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.
