R: Convert a numeric or character vector into an optimizer...

as.statusCode {OpenMx} | R Documentation

## Convert a numeric or character vector into an optimizer status code factor

### Description

- 0,‘OK’: Optimization succeeded

- 1,‘OK/green’: Optimization succeeded, but the sequence of iterates has not yet converged (Mx status GREEN). This condition is only detected by NPSOL.

- 2,‘infeasible linear constraint’: The linear constraints and bounds could not be satisfied. The problem has no feasible solution.

- 3,‘infeasible non-linear constraint’: The nonlinear constraints and bounds could not be satisfied. The problem may have no feasible solution.

- 4,‘iteration limit’: Optimization was stopped prematurely because the iteration limit was reached (Mx status BLUE). You might want to rerun: `m1 = mxRun(m1)` or increase the iteration limit (see `mxOption`).

- 5,‘not convex’: The Hessian at the solution does not appear to be convex (Mx status RED). There may be more than one solution to the model. See `mxCheckIdentification`.

- 6,‘nonzero gradient’: The model does not satisfy the first-order optimality conditions to the required accuracy, and no improved point for the merit function could be found during the final linesearch (Mx status RED). To search nearby, see `mxTryHard`.

- 7,‘bad deriv’: You have provided analytic derivatives. However, your provided derivatives differ too much from numerically approximated derivatives. Double check your math.

- 9,‘internal error’: An input parameter was invalid. The most likely cause is a bug in the code. Please report occurrences to the OpenMx developers.

- 10,‘infeasible start’: Starting values were infeasible. Modify the start values for one or more parameters. For instance, set means to their measured value, or set variances and covariances to plausible values. See `mxAutoStart` and `mxTryHard`.
