1Blurb:: 2Turn on regression diagnostics 3Description:: 4When \c regression_diagnostics (NL2SOL's \c rdreq) is specified and a 5positive-definite final Hessian approximation H is computed, NL2SOL 6computes and prints a regression diagnostic vector RD such that if 7omitting the i-th observation would cause alpha times the change in 8the solution that omitting the j-th observation would cause, then 9RD[i] = |alpha| RD[j]. The finite-difference step-size tolerance 10affecting H is \ref responses-numerical_hessians-fd_step_size (NL2SOL's \c delta0 and \c 11dltfdc). 12 13 14Topics:: 15Examples:: 16Theory:: 17Faq:: 18See_Also:: 19
