nonlinear regression; confidence regions; weak intrinsic and weak parameter-effects curvatures; linear approximation; curvature measures; quadratic approximations; likelihood ratios
Summary:
New curvature measures for nonlinear regression models are developed and methods of their computing are given. Using these measures, more accurate confidence regions for parameters than those based on linear or quadratic approximations are obtained.
