Hi everyone,

 

My question: I have a dataset with three columns [ID $; Group (class variable); Value (continuous)] - sample code provided below.

 

My goal: change values for group 0 to be equivalent to the values for group 1 (by equivalent I want both groups to have same average).

 

The problem: I can't make up values. A member (ID) from Group 0 *must* take a value from group 1 (doesn't matter who) and the program needs to terminate once the averages between the two groups are equivalent (or ideally a user specified tolerance, say 1% or 5% within each other). The other problem is that the dataset has dozens of other records that I need to retain, so do not want to transpose. Exporting the Group=1 into a new dataset and then re-joining to the original is fine, but I would like the structure to remain in tact. 

 

Appreciate the help if someone has some time. Happy to clarify. Kind regards, Nate
