Testing under local misspecification and artificial regressions
An additivity property of LM tests is derived, linking joint, marginal and Bera-Yoon "adjusted" tests, hence the latter can be derived as the difference of the first two. An artificial regression framework provides an intuitive geometrical illustration of the Bera-Yoon principle.
