NonLinear Fit locking parameters

BijuP — Fri, 09 Jun 2023 00:53:34 GMT

Hello JMP Gurus,

I am using the JMP NonLinear platform fit for fitting a 6-parameter model for 2 categories (using By). I am providing reasonably good initial guesses for the parameters.

1) I would like to lock 2 of the 6 parameters for a first iteration for easier convergence. How can this be done via JSL?

2) I would like to first run with the 2 locked parameters, and after the first "Go" converges, would like to unlock the 2 parameters & re-run the fit again to finish. How can this be done via JSL?

3) How to do 1) & 2) for each of the two By categories individually?

I am using JPM14Pro. Attached a snapshot of the NL platform on launch.

Thanks!

Take a look at the scripting index. Help>Scripting Index

There are a bunch of example scripts for controlling the non-linear platform
