Procedimiento y algoritmo de estimación en modelos multinivel para proporciones

open access: yesRevista Colombiana de Estadística, 2010
En este artículo se describe un procedimiento para la estimación de parámetros fijos y aleatorios en modelos multinivel para proporciones. El procedimiento de estimación se basa en el método de los mínimos cuadrados generalizados.

Convergence analysis of generalized iteratively reweighted least squares algorithms on convex function spaces [PDF]

open access: yes
The computation of robust regression estimates often relies on minimization of a convex functional on a convex set. In this paper we discuss a general technique for a large class of convex functionals to compute the minimizers iteratively which is ...

$\ell_1$-Regularized Generalized Least Squares

open access: yes
We study an $\ell_{1}$-regularized generalized least-squares (GLS) estimator for high-dimensional regressions with autocorrelated errors. Specifically, we consider the case where errors are assumed to follow an autoregressive process, alongside a feasible variant of GLS that estimates the structure of this process in a data-driven manner.

Integer-Valued Moving Average Modelling of the Number of Transactions in Stocks [PDF]

open access: yes
The integer-valued moving average model is advanced to model the number of transactions in intra-day data of stocks. The conditional mean and variance properties are discussed and model extensions to include, e.g., explanatory variables are offered ...

Competitiveness – A Comparison of China and Mexico [PDF]

open access: yes
Latin American countries have lost competitiveness in world markets in comparison to China over the last two decades. The main purpose of this study is to examine the causes of this development. To this end an augmented Ricardian model is estimated using
