Is this a variation on a residual plot?

  1. May 4, 2014 #1
    Hi all,

    Consider the scatter plot below (example only):


    The bottom subplot looks like a residual plot (y-x), but it's over (1+x). I'm hoping someone can explain what this is and the benefit of it.

    Maybe the uncertainty is expected to scale with 1+x?

    Based on what type of data it is, I think you're correct. Thanks.
