We have revised the paper Inference for Functions of Partially Identified Parameters Defined by Moment Inequalities. The paper has been significantly edited and the new description is friendlier to practitioners. Section 2 includes a step by step guide to implement our test, without getting into technical details. Section 3 includes a new and simple example that illustrates why a naive GMS approach does not deliver a valid test and why the new test we propose does not suffer from similar problems. The technical aspects, including the formal results, are in Section 4 now.
