I thought I posted this already but I can no longer find the post so it might not have posted correctly. Please delete if duplicated. My question:

What iteration algorithm is adopted by OriginLab for fitting when using the Rank Models app?

Origin Ver. and Service Release (Select Help-->About Origin): 9.7.0.188 (Academic)
Operating System: Windows 10

Hi,

Levenberg-Marquardt (L-M) algorithm is used. Please see details in this page:
