Hello!

I read that parameter dependency in NLSF is defined by 1 - 1 / (C_ii * C_ii^-1) where C_ii is the diagonal element of the variance-covariance matrix.

This equation seems incorrect as the C_ii eliminate each other. Can anybody give more details on the equations used by Origin to calculate parameter dependency?
Thanks,

A. Horn

C_ii^-1 is the ii'th diagonal element of the inverse of matrix C, not the inverse of C_ii.
