Problem with loop modelling output saving

Hi

 

I have a Data set with Client ID | Order ID | Quantity | Price, what I want to do is a regression per client ID  like Quantity = Beta + alpha*Price and save the output in a collection, I got to the collection but it keeps printing the same value over and over again, also I would like to append the Client ID to their respective model but I dont know how, could someone help me please?

 

Thanks

    Hi,

    attached is a solution. You need Operator Toolbox extension to run this.

     

    Best,

    @sebastian_gonza,

    did you use macros? Attached a version with annotate.

     

    Cheers,
