Verifying the Solution from a Nonlinear Solver: A Case Study.

| Sumario: | The textbook paradigm has ignored computational reality by accepting uncritically the output from a computer program's nonlinear procedure for probit estimation. As the example of Houston Stokes makes clear, the fact that a computer software package produces a solution to an estimation problem does not necessarily mean either that the solution is accurate or that a solution exists. A four-step process for verifying solutions to probit estimation is presented. |
