This article describes the conditions imposed, the constraints and the solutions that are specific to statistical research in the broad field of ecology, materialized within the limited range of urban waste. Exhaustive investigation and analysis of the general and local, as well as the...

Before formulating the statistical hypotheses and the econometric testing itself, a breakdown of some of the technical issues is required, which are related to managerial decision in innovative educational systems, the educational managerial phenomenon tested through statistical and mathematical...

Dynamic provisions could help to enhance the solvency of individual banks and reduce procyclicality. Accomplishing these objectives depends on country-specific features of the banking system, business practices, and the calibration of the dynamic provisions scheme. In the case of Chile, a...

The paper developes a VAR macrofinance model of the Czech economy. It shows that yield misalignments from the yields implied by the macrofinance model partially determine subsequent yield changes over three to nine months. These yield misalignments tend to persist for a number of months. This...

A simple graphical approach to presenting results from nonlinear regression models is described. In the face of multiple covariates, 'partial mean' plots may be unattractive. The approach here is portable to a variety of settings and can be tailored to the specific application at hand. A simple...

The early history of the partial equilibrium demand-and-supply-curve diagram confirms the adage that no scientific discovery is named for its original discoverer. For it was not Alfred Marshall but five of his predecessors who introduced the diagram associated with his name

This article uses graph theory to provide novel evidence regarding market integration, a favorable condition for systemic risk to appear in. Relying on daily futures returns covering a 12-year period, we examine cross- and inter-market linkages, both within the commodity complex and between...

Due to the Sarbanes-Oxley Act (SOX), new rules that require independent directors on corporate boards and committees are likely to create overlapping board structures (when a director serves on more than one committee). The purpose of this study is to examine the effects of independent and...

This paper deals with the Bayesian analysis of graphical models of marginal independence for three way contingency tables. Each marginal independence model corresponds to a particular factorization of the cell probabilities and a conjugate analysis based on Dirichlet prior can be performed. We...
