Re: How do I get "Group Y by..." option in "Fit Y by X" platform (why it doesn't work)

Can you explain how it's not working for you? The Group By option will cause the Fit commands to perform one fit for each level of the grouping variable.

 

I used your data table and and ran Fit Y by X with myX and myY respectively.

Then I chose the "Group By..." option from the Bivariate menu and used Name as the Grouping variable.

Then fit a line and got this result:

First,  welcome to the community.

 

Use the Group by when running the platform Fit Y by X.  I have added the script to your data table.
