How to use mode in multimodal set in QlikView expression?

Question

Mode function in QlikView will return the mode element in array, only if there is only one. If there is more than one it returns null.

I need to return list of Modes in someway in a expression.

How can I return the list of modes in a multimodal set like:

1 3 3 5 5 7 9

I would to return 3, 5. So I can take Min, or Max, or Avg..

Answer 1

I just needed to read up on Multimodals, so correct me if I'm wrong. This expression returns the highest of the two values that has the highest number of occurances (right?):

Max( 
 Aggr ( 
  if (count( Num)>=Max(total Aggr(count( Num),Num)) ,Num),
  Num)
)

I use the Aggr function to create the list to pick from. So change the first Max to whatever you want to pick.
