We pose a monotonicity conjecture on the number of pseudo-triangulations of any planar point set, and check it in two prominent families of point sets, namely the so-called double circle and double chain. The latter has asymptotically 12n pointed pseudo-triangulations, which lies significantly above the maximum number of triangulations in a planar point set known so far.

Abstract The main goal of the paper concerns two parts, in ˝rst one, we extend some results from Blot et al [5] under general hypothesis on measure, second part, introduce a new class functions, which call measure pseudo

This paper investigates the potential problem of ‘pseudo-exogenous’ instruments in regression models. We show that the performance of Hausman test is deteriorated when the instruments are asymptotically exogenous but endogenous in finite samples, through Monte Carlo simulations.

Well known encompassing tests are usually difficult to implement because it is difficult to compute the pseudo-true value of the quasi-maximum likelihood estimator. In this paper, we propose a more operational encompassing test that does not involve such pseudo-true value. Instead, the proposed test relies on the “pseudo-true score” which is relatively easier to evaluate. We show that this test...

We study pseudo-simple heteroclinic cycles for a Γ-equivariant system in R4 withfinite Γ ⊂ O(4), and their nearby dynamics. In particular, in a first step towardsa full classification – analogous to that which exists already for the class of simplecycles – we identify all finite subgroups of O(4) admitting pseudo-simple cycles. Tothis end we introduce a constructive method t...
