Need help: in calculated metric by dividing specific month vs last year's month

[brandonc6001189]

Hello,

I'm in the process of creating an engagement score using the calculated metrics in Workspace (essentially, an aggregate of 7 metrics that is indexed from previous year's same month and then weighted). 

Is there a way to have Adobe Analytics divide a month to its previous year's month (13 months back)?  So, January 2019 vs January 2018, etc.  This would be in the Calculated Metrics section of Workspace.

Thank you!

basically you could create a segment with the desired "date range" in it. so create 2 "hit-segments" with date ranges "13 month ago" and "last month" in it. then create the calc. metric by applying the segments to the desired metrics.
