Group testing is an efficient method of conducting massive tests using limited resources. We consider a group testing problem with the aim of deriving an optimal partition policy that minimizes the systematic objective, which is the weighted sum of the expected false-negative classifications,...

We suggest a robust form of conditional moment test as a constructive test for functional misspecification in multiplicative error models. The proposed test has power solely against violations of the conditional mean restriction but is not affected by any other type of model misspecification....
