USE OF TRANSFORMATIONS ON PARAMETERS IN NON-LINEAR THEORY. Ⅱ. MEASURES OF NON-LINEARITY AND TRANSFORMATIONS TO REDUCE NON-LINEARITY

摘要

In the first of these two papers, the authors (1964) have discussed the use of transformations on parameters designed to accelerate convergence in non-linear least squares problems. In this paper, we continue our discussion of non-linear least squares problems, and turn attention to measures of non-linearity.
