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 ...
Numerical Distribution Functions for Seasonal Unit Root Tests
(2011-12)
When working with time series data observed at intervals smaller than a year, it is often necessary to test for the presence of seasonal unit roots. One of the most widely used methods for testing seasonal unit roots is ...
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 ...
Using discrete choice experiments for environmental valuation
(2010)
This paper provides with a review of the state of the art of environmental valuation with discrete choice experiments (DCE). The growing body of literature on this field serves to emphasise the increasing role that DCE are ...
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 ...
Stochastic Surface Models for Commodity Futures: A 2D Kalman Filter Approach
(2011-09)
We propose a two-dimensional Kalman filter approach that, additional to the information contained in futures prices evolution over time, makes use of information contained in the term structure of commodity futures along ...
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 ...
