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.
The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.
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.
