We focus on two main issues that typically arise in econometrics. First, many econometric models are estimated through maximum likelihood or pseudoML methods like, for example, limited dependent variable or gravity models. Second, often one might not want to fully specify the null hypothesis. Instead, one would rather impose some structure like separability or monotonicity. In order to address these points we introduce an adaptive omnibus test. Special emphasis is given to practical issues like adaptive bandwidth choice, general but simple requirements on the estimates, and finite sample performance, including the resampling approximations.}, organization = {We acknowledge financial support from FUNCAS, the Spanish Projects MTM2008-03010 and ECO2010-15455, and the DAAD Project 50119348.}, publisher = {Cambridge University Press}, publisher = {Econometric Theory, 2015, 31(6), 1281-1309}, title = {Specification testing when the null is nonparametric or semiparametric}, author = {Rodríguez-Poo, Juan M. and Sperlich, Stefan and Vieu, Philippe}, }
