Turn on regression diagnostics
Alias: none
Argument(s): none
Default: no regression diagnostics
When regression_diagnostics
(NL2SOL's rdreq
) is specified and a positive-definite final Hessian approximation H is computed, NL2SOL computes and prints a regression diagnostic vector RD such that if omitting the i-th observation would cause alpha times the change in the solution that omitting the j-th observation would cause, then RD[i] = |alpha| RD[j]. The finite-difference step-size tolerance affecting H is fd_step_size (NL2SOL's delta0
and dltfdc
).
