Semiparametric inference in correlated long memory signal plus noise models
(2010-04)
This paper proposes an extension of the log periodogram regression in perturbed long memory series that accounts for the added noise, also allowing for correlation between signal and noise, which represents a common situation ...
Doubly fractional models for dynamic heteroskedastic cycles
(2011-02)
Strong persistence is a common phenomenon that has been documented not only in the levels but also in the volatility of many time series. The class of doubly fractional models is extended to include the possibility of long ...
Fractional Integration Analysis and its Implications on Profitability: the Case of the Mackerel Market in the Basque Country
(2010)
This paper analyses weekly prices for mackerel landed by the inshore fleet at the ports of the Basque Country in 1995-2008, using new econometric techniques never before applied to the fishing market. The idea is to learn ...
Analysis of volatility transmissions in integrated and interconnected markets: The case of the Iberian and French markets
(2012)
This paper models the mean and volatility spillovers of prices within the integrated Iberian and the interconnected Spanish and French electricity markets. Using the constant (CCC) and dynamic conditional correlation (DCC) ...
Wavelet multiple correlation and cross-correlation: A multiscale analysis of euro zone stock markets
(2011-06)
Statistical studies that consider multiscale relationships among several variables use wavelet correlations and cross-correlations between pairs of variables. This procedure needs to calculate and compare a large number ...
A Note on Wavelet Correlation and Cointegration
(2013-11)
In a recent paper Leong-Huang:2010 {Journal of Applied Statistics 37, 215–233} proposed a wavelet-correlation-based approach to test for cointegration between two time series.
However, correlation and cointegration are ...
Seasonal Stability Tests in gretl. An Application to International Tourism Data
(2013-09)
The seasonal stability tests of Canova & Hansen (1995) (CH) provide a method complementary to that of Hylleberg et al. (1990) for testing for seasonal unit roots. But the distribution of the CH tests are unknown in small ...
Lagrangean decomposition for large-scale two-stage stochastic mixed 0-1 problems
(2010-07)
In this paper we study solution methods for solving the dual problem corresponding to the Lagrangean Decomposition of two stage stochastic mixed 0-1 models. We represent the two stage stochastic mixed 0-1 problem by a ...
On downloading and using COIN-OR for solving linear/integer optimization problems
(2010)
The aim of this technical report is to present some detailed explanations in order to help to use the open source software for optimization COIN-OR. In particular, we describe how to download, install and use the corresponding ...
A note on the implementation of the BFC-MSMIP algorithm in C++ by using COIN-OR as an optimization engine
(2010)
The aim of this technical report is to present some detailed explanations in order to help to understand and use the algorithm Branch and Fix Coordination for solving MultiStage Mixed Integer Problems (BFC- MSMIP). We have ...
