Several recent studies have expressed concern that the Haar prior typically imposed in estimating sign-identified VAR models may be unintentionally informative about the implied prior for the structural impulse responses. This question is indeed important, but we show that the tools that have...

Abstract The present work aims to propose an approximation of the sample median distribution with a normal parent distribution. Although the mean is usually used as the central tendency measure for normal samples, the median has also been used in engineering, process control in particular. The...

__Abstract__ A median (antimedian) of a profile of vertices on a graph $G$ is a vertex that minimizes (maximizes) the remoteness value, that is, the sum of the distances to the elements in the profile. The median (or antimedian) function has as output the set of medians (antimedians) of a...

We argue that survey-based median household consumption expenditure (or income) per capita be incorporated into standard development indicators, as a simple, robust, and durable indicator of typical individual material well-being in a country. Using household survey data available for low- and...

One of the methods to estimate the poverty level inside a given population is based on how to define the poverty line values. Each person having his income under the poverty threshold will be considered to be poor. In the literature we distinguish at least three approaches: to evaluate the...

In the framework of spatial competition, two or more players strategically choose a location in order to attract consumers. It is assumed standardly that consumers with the same favorite location fully agree on the ranking of all possible locations. To investigate the necessity of this...

This paper presents a brief analysis of representative measures of inflation expectations from Central Bank of Brazil's Survey of Professional Forecasts that are alternative to the median response. We build time series with the mode and core measures of inflation expectations from the panel of...

This paper investigates inequality in health both between and within different socioeconomic groups as well as over time in Denmark. We use selfreported health as a holistic measure of health. Inequalities in selfreported health are challenging to analyze due to its qualitative nature. We review...

The median problem is a classical problem in Location Theory: one searches for a location that minimizes the average distance to the sites of the clients. This is for desired facilities as a distribution center for a set of warehouses. More recently, for obnoxious facilities, the antimedian was...

A profile = (x1, ..., xk), of length k, in a finite connected graph G is a sequence of vertices of G, with repetitions allowed. A median x of is a vertex for which the sum of the distances from x to the vertices in the profile is minimum. The median function finds the set of all medians of a...

This study analyzes the minimum quality standard set by the European Union (EU) through Regulation 1371/2007 of Rail Passengers' Rights and Obligations. A welfare maximizing quality standard raises quality and consumer satisfaction, but does not improve the modal split of rail transport. A...

The general problem in location theory deals with functions that find sites on a graph (discrete case) or network (continuous case) in such a way as to minimize some cost (or maximize some benefit) to a given set of clients represented by vertices on the graph or points on the network. The...

This paper deals with estimating data from experiments determining lottery certainty equivalents. The paper presents the parametric and nonparametric results of the least squares (mean), quantile (including median) and mode estimations. The examined data are found to be positively skewed for low...

This paper presents a regression procedure for inhomogeneous data characterized by varying variance, skewness and kurtosis or by an unequal amount of data over the estimation domain. The concept is based first on the estimation of the densities of an observed variable for given values of...

This paper is an attempt to fill the knowledge of the role played by network in the labor market assimilation of immigrants and the mechanisms through which networks affect the labor market outcomes of recent immigrants.

This article surveys seven directions of consensus theories: Arrowian results, federation consensus rules, metric consensus rules, tournament solutions, restricted domains, abstract consensus theories, algorithmic and complexity issues. This survey is oriented in the sense that it is mainly –...

This paper presents the -linked- notions of metric and latticial medians and it explains what is the median procedure for the consensus problems, in particular in the case of the aggregation of linear orders. First we consider the medians of a v-tuple of arbitrary or particular binary...

Least absolute deviations (LAD) estimation of linear time-series models is considered under conditional heteroskedasticity and serial correlation. The limit theory of the LAD estimator is obtained without assuming the finite density condition for the errors that is required in standard LAD...

Stata’s main data model treats observations in rows and variables in columns quite differently, but rowwise problems also arise that require working against the grain. This column shows how to exploit existing functions and egen functions when they exist and apply to such problems. It offers...

We consider one-to-one, one-sided matching (roommate) problems in which agents can either be matched as pairs or remain single. We introduce a so-called bi-choice graph for each pair of stable matchings and characterize its structure. Exploiting this structure we obtain as a corollary the "lone...

We present three generalized, empirical, economic inequality definitions for the empirical dominance of the income distribution of Population 1 over that of Population 2 with respect to their n-person economy in terms of a general transformation function G. These definitions are based on the...

The analysis of the empirical distribution of univariate data often includes the computation of location, scale, skewness, and tail-heaviness measures, which are estimates of specific parameters of the underlying population distribution. Several measures are available, but they differ by...
