This note shows that the asymptotic variance of Chen’s [Econometrica, 70, 4 (2002), 1683–1697] two-step estimator of the link function in a linear transformation model depends on

In contrast, a systematic study of small degree embeddings (see in particular § 4.2) reveals that the images of these rational smooth embeddings are in a natural way smooth fibers of

Second, in the case some support for the DSGE model is found in the data when evaluated against the larger information set (the optimal λ in the DSGE-FAVAR is different from zero),

The essential idea of this method, as ap- plied to spin 1/2 systems, is to construct cells on the lattice, in such a way that the ground state of the Hamiltonian - if

Le Cam’s theory has found applications in several problem in statistical decision theory and it has been developed, for example, for non- parametric regression, nonparametric

As different bound states are described by the same sigma-model as in the case of single extremal branes, we will first look at a general SL(3, R)/SO(2, 1) sigma-model.. This model

In Sections 2 and 3, we introduce the notions of transition energy function and of (one-point) transi- tion energy field, and show that the representation in Gibbsian form is
