摘要:
In the first paper of this series, it was shown that the least-squares solutions for the nonlinear parameters of weighted sum models, as multiexponentials, may pairwise exactly coincide. This was explained as a consequence of degeneracy of the least-squares criterion under the influence of errors. This theory is now extended to include the coincidence of more than two nonlinear parameters.
