Inference for a Special Bilinear Time Series Model

open access: yes, 2014
It is well known that estimating bilinear models is quite challenging. Many different ideas have been proposed to solve this problem. However, there is not a simple way to do inference even for its simple cases.

Asymptotic theory of least squares estimators for nearly unstable processes under strong dependence

open access: yes, 2007
This paper considers the effect of least squares procedures for nearly unstable linear time series with strongly dependent innovations. Under a general framework and appropriate scaling, it is shown that ordinary least squares procedures converge to ...

Wavelet-Based Prediction for Governance, Diversification and Value Creation Variables [PDF]

open access: yes, 2010
We study the possibility of completing data bases of a sample of governance, diversification and value creation variables by providing a well adapted method to reconstruct the missing parts in order to obtain a complete sample to be applied for testing ...

Nonlinear Cointegration and Nonlinear Error Correction: Record Counting Cointegration Tests. [PDF]

open access: yes
In this article we propose a record counting cointegration (RCC) test that is robust to nonlinearities and certain types of structural breaks. The RCC test is based on the synchronicity property of the jumps (new records) of cointegrated series, counting

Uniform Limit Theory for Stationary Autoregression [PDF]

open access: yes
First order autoregression is shown to satisfy a limit theory which is uniform over stationary values of the autoregressive coefficient rho = rho_{n} in [0,1) provided (1 - rho_{n})n approaches infinity.

Persistence exponent for discrete-time, time-reversible processes

open access: yes, 2015
We study the persistence probability for some discrete-time, time-reversible processes. In particular, we deduce the persistence exponent in a number of examples: first, we deal with random walks in random sceneries (RWRS) in any dimension with Gaussian ...
