How to find error between non-linear plot and data points?

  1. Feb 21, 2013 #1
    Is there a formal way to measure the error between some arbitrary points and a non-linear curve in order to minimize it?

    The short answer is "yes".
    You can regress to a curve in many ways... least-squares is popular.
    What's best depends on the curve and what you want to know.
    I'm guessing you already know how to regress to a line?
