Ordered categorical panel data is modeled assuming an underlying continuous-time finite-space Markov chain. The tridiagonal form of the intensity matrix renders the implementation of the maximum likelihood method more ...

We present the aggregated excess demand functions in an exchange economy. We study the properties and the equilibrium price vector of the aggregated excess demand functions. We prove that the walrasian equilibrium is a ...

In the part, we present a factorial approach for clustering following the least squares criterion, for every choice of the metrics in the individual space. We deduce that the between-clusters inertia has an upper bound ...

Two methods for analyzing multiple data tables of the French Data Analysis school are presented: the Statis method and Multiple Factor Analysis. The types of data that can be trated by each methodology area analyzed and ...

We consider the general linear model with the classical hypothesis. In particular we consider the variance analysis in two factors and we give explicitly the forms of the associated matrixes as well as the statistics of ...

Given a set of categorical variables, we want to predict one or more of them by the way rules. We propose an algorithm that (i) is guided by statistical results in a relational geometry where we use assymetrical association ...

In this work we present some significative sets of functions. Following the ideas of [2] we introduce the almost periodic functions and its elementary properties. Based in [12] we give a clasification of the sets.

Manly and Parr in 1968 obtain a model which give an estimation of the parameters of an animal population. The model presents some weakness on the specifications of the class of individual in the population. In the present ...

A new proof of the existence of minimal models of the hiperreal line is obtained in terms of a combinatorial property of Ramsey ultrafilters over a countable set.
