    fitting non linear trend lines to a log log graph

    Andrei Ilas

      Hi all,

       

      I want to fit a nonlinear trend on a log log graph. I managed to integrate R in Tableau and created a linear trend using the formula:

      SCRIPT_REAL(

      ” tl <- lm( .arg2 ~ .arg1)

      tl$fitted ” ,

                SUM([x]), SUM([y]))

      However, this is not what I am looking for. From my research, it should be something with the nls function in R, but I am beginner in R and cannot write the function myself. Can you please help me with some suggestions?

       

      In Excel, it's a click distance to get the non-linear trend with the equation description.

       

      Your help is much appreciated.
