This paper introduces in statistics the notion of the barycenter of the distribution of a non-negative random variable and explores its relation with the Gini index, the concentration area, and the Gini’s mean difference. The introduction of the barycenter allows for new economic, geometrical,...

The three pillars of econometric modeling are: (1) the reduced form, (2) the recursive form, and (3) the structural form. Each of these techniques exists for the purpose of revealing the joint conditional probability distributions of current and lagged endogenous variables conditional on the...

Data analysis is an ever-evolving subject and is of utmost importance and priority for research as well as researcher. It encompasses inspection, coding, transformation, and modelling to draw scientific conclusions. In the recent past, data mining and use of quantitative techniques has been...

The purpose of this editorial is to discuss methodological advancements to enhance quantitative theory-testing entrepreneurship research. As the impact of entrepreneurship scholarship accelerates and deepens, our methods must keep pace to continue shaping theory, policy, and practice. Like our...

This paper introduces in statistics the notion of the barycenter of the distribution of a non-negative random variable Y with a positive finite mean μY and the quantile function Q(x). The barycenter is denoted by μX and defined as the expected value of the random variable X having the...

Bayesian networks are multivariate statistical models using a directed acyclic graph to represent statistical dependencies among variables. When dealing with Bayesian Networks it is common to assume that all the variables are discrete. This is not often the case in many real contexts where also...

A concept and mathematical model of modern economics are formulated in which a company profit is defined when taking into account possible interests of individual decision makers rather than based exclusively on benefits of either the company (ground of microeconomics) or the whole society...

We consider inference on optimal treatment assignments. Our methods allow for inference on the treatment assignment rule that would be optimal given knowledge of the population treatment effect in a general setting. The procedure uses multiple hypothesis testing methods to determine a subset of...
