Generate Attribute to find 2nd and 3rd minimums

edited November 2024 in Community Q&A
Have a large set 17 atts, ~1.6 mil rows. Looking to generate 3 attributes; minimum, 2nd min, 3rd min of each row. The first minimum is simple using the generate aggregation block but after that it gets messy. I can think of a few ways to do this, setting a macro of the min and doing 2 huge if statement sets in generate attributes where it checks every att to see if it matches the min val and returning missing else returning the value ect or a loop with transpose and sorting but these seem a bit in-elegant. Any simpler methods I am missing?

    Hey @ZKuiper

    I can think of a leaner way to do this utilizing one sorting that can help you extract all the mins together as macros. Check out the XML.

    For the time being I have used a transpose, loop atts, and sort to get the job done. I still feel like there is a better way but this will do for now.

    I can think of a leaner way to do this utilizing one sorting that can help you extract all the mins together as macros. Check out the XML.
