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