The development trend of the oil-rich United Arab Emirates (UAE) is at the heart of debates surrounding the effects of culture on economic choices and out.

Chafik Bouhaddioui Proton exchange membrane fuel cell (PEMFC) is the most common type of fuel cell because of its many advantages over other renewable energy sources and other fuel cell types.

The PEMFC is used for power and electric vehicle applications.

Static and dynamic characteristics are of vital importance; the PEMFC has been modeled in numerous research using.

In this paper, we apply Multiple Linear Regression (MLR) to develop a trust model for processing Big Data over diverse Clouds.

Chafik Bouhaddioui Data is the most valuable asset companies are proud of.

When its quality degrades, the consequences are unpredictable and can lead to complete wrong insights.

In Big Data context, evaluating the data quality is challenging and must be done prior to any Big data analytics by providing some data quality confidence.

View Interval estimation of variance ratio in non-normal unbalanced one-way random models Article Jun 2014 Chafik Bouhaddioui Mohamed Y.

Since the proposed procedure is heavily dependent on the estimation of the kurtosis of the underlying distributio.

View Empirical Processes for Infinite Variance Autoregressive Models Article Jun 2011 Kilani Ghoudi Chafik Bouhaddioui The paper proposes new procedures for diagnostic checking of fitted models under the assumption of infinite-variance errors which are in the domain of attraction of a stable law.

These procedures are functional of residual-based empirical processes.

First, the asymptotic distributions of the empirical processes based on residuals are derived.

Then. View Semiparametric Innovation-Based Tests of Orthogonality and Causality between Two Infinite-Order Cointegrated Ceries with Application to CanadaUS Monetary Interactions Article Mar 2011 Chafik Bouhaddioui Jean-Marie Dufour We propose a semi-parametric approach for testing orthogonality and causality between two infinite-order co-integrated vector auto-regressive IVAR(1) series.

The procedures considered can be viewed as extensions of classical methods proposed by Haugh (1976, JASA) and Hong (1996, Biometrika) for testing independence between stationary univariate tim.

View Tests for Non-Correlation of Two Infinite-Order Cointegrated Vector Au-toregressive Series Article Full-text available Jan 2008 Chafik Bouhaddioui Jean-Marie Dufour We propose two approaches for testing non-correlation between the innovations of two nonstationary possibly cointegrated vector processes, in the general case where the processes have infinite-order autoregressive representations.

The first approach is based on cross-correlation matrices, while the second approach uses partial cross-correlation mat.

View A Generalized Portmanteau Test For Independence Of Two Infinite-Order Vector Autoregressive Series Article Jul 2006 Chafik Bouhaddioui Roch Roy In many situations, we want to verify the existence of a relationship between multivariate time series.

Here, we propose a semiparametric approach for testing the independence between two infinite-order vector autoregressive (VAR(infinity)) series, which is an extension of Hongs Biometrika (1996c) vol.

We first fi. View On the distribution of the residual cross-correlations of infinite order vector autoregressive series and applications Article Full-text available Jan 2006 Chafik Bouhaddioui Roch Roy Here we derive the asymptotic distribution of an arbitrary vector of residual cross-correlations resulting from the fitting of finite autoregressions to two uncorrelated infinite order vector autoregressive series.

Its asymptotic distribution is the same multivariate normal as the one of the corresponding vector of cross-correlations between the tw.
