Can JMP compute Duan's smearing estimator (Duan, 1983) for retransformations

Hi - I just modeled, using multiple linear regression, log Ecoli in terms of log turbidity and a rainfall variable and now need to retransform the Ecoli results back into arithmetic form. This retransformation technique was used to good effect in a similar project (USGS OFR 2020-1048). I can't find any reference to it in JMP.

Any suggestions? Thanks in advance!

I suggest that you save the residuals from the fitting platform, then create a new data column with another formula to implement transformation. Then use Summary, Distribution, or Tabulate to calculate the smearing estimator (average back-transformed residual).
