Compositional data analysis is carried out either by neglecting the compositional constraint and applying standard multivariate data analysis, or by transforming the data using the logs of the ratios of the components. In this work we examine a more general transformation which includes both...

Latent budget analysis is a classification technique that allows clustering identification by using compositional data. This paper presents examples of how this technique deals with the unit-sum constraint by establishing an initial independence model to which subsequent models are compared in...

Évora (county and above all, the city) is often cited as a case of success in terms of regional development, as it stands out in terms of social, economic, and demographic indicators from the rest of the region where it is located, i.e. the Alentejo (Portugal). This fact makes it relevant: (i)...

During the recent decades the higher education system in Portugal has experienced structural changes, including the substantial increase in the number of higher education institutions, scattered throughout the territory, in parallel with the increasing number of students and teachers. Recently,...

The aim of this work is to find patterns for products included in the customs tariffs of the USA and the EU (composed of over 5000 products disaggregated at the 6 digit-level) which share similarities, defined by a set of international trade variables, namely the index of revealed comparative...

Using data from our own household survey (n=477) in Hanoi's peri-urban areas, this paper attempts to answer (i) what livelihood strategies are pursued by peri-urban households, (ii) which strategies are lucrative and which are not, and (iii) whether access to farmland is the potential barrier to...

The paper presents an estimate of the expenditure requirements to be used as a benchmark in the identification of best practices in the spending behavior of the municipalities. In order to distinguish the determinants of theoretical expenditure requirements with respect to those relating to...

A recent transition in the field of agrarian economics theory for rural development is the move from a narrow agricultural sector approach, to one which adopts broader territorial vision. This passage seeks to interpret interactions between urban and rural worlds in a more comprehensive...

The aim of this work is to find patterns for products included in the customs tariffs of the USA and the EU (composed of over 5000 products disaggregated at the 6 digit-level) which share similarities, defined by a set of international trade variables, namely the index of revealed comparative...

This paper has as main objective to present and to test a tool of multivariate statistics in financial models. This methodology, known as clusters analysis, separates the observations in groups through its determined characteristic, in contrast of the traditional methodology, which is only the...
