We show that the asymptotic mean of the log-likelihood ratio in a misspecified model is a differential geometric quantity that is related to the exponential curvature of Efron (1978), Amari (1982), and the preferred point geometry of Critchley et al. (1993, 1994). The mean is invariant with...

The partial (ceteris paribus) effects of interest in nonlinear and interactive linear models are heterogeneous as they can vary dramatically with the underlying observed or unobserved covariates. Despite the apparent importance of heterogeneity, a common practice in modern empirical work is to...

The issue of the non-invariance of the Wald test under nonlinear reparametrisations of the restrictions under test is studied from a differential geometric viewpoint. Quantities that can be defined in purely geometrical terms are by construction invariant under reparametrisation, and various...

The problem of selecting a clustering algorithm from the myriad of algorithms has been discussed in recent years. Many researchers have attacked this problem by using the concept of admissibility (e.g. Fisher and Van Ness, 1971, Yadohisa, et al., 1999). We propose a new criterion called the...

Organizational theory has construed complexity as an objective characteristic of either the structure or the behaviour … structure or behavior. This cognitive twist is illustrated using two theoretical approaches, whose relationship is discussed. …

High mortality conditioned by both endogenous and exogenous causes is one of the challenges of today that will restrict the development of Russian regions and modernization of the economy. The paper presents the results of a multidimensional typological analysis of the subjects of the Russian...

Managerial perception is the process by which managers form an image of the stimuli they receive. According to research, perception is conditioned by the individual's cognitive profile. But the different nature of incoming stimuli suggests that it would be interesting to study whether the...
