Hello,

 

I need to create a new variable that contains the answer with the highest frequency across variables (SAS version 9.4). For example:

id  var

100 2

100 2

100 2

100 4

100 5

101 3

101 3

101 1

101 2

101 3

102 4

102 4

102 5

102 2

102 1

 

I want to add a new variable, so that:

id newvar

100 2

101 3

102 4

 

It seems like there should be a relatively simple answer, but can't seem to figure out. I can transpose to wide if that is better. Any advice will be great, thanks!
