Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

Hello,

I am trying to use 3dNLfim to perform nonlinear least square fitting on the following model:

Y[t] = A*X[t] + B*Z[t].

I know Y[t], X[t] and Z[t], and I want to estimate A and B.
I was thinking to use 3dNLfim Expr2 model, but I am not sure how to set up the command. Any suggestion is very much appreciated.

Thank you,
Giuseppe
