In this paper we use the Bayesian Structural VAR framework to identify the major shock monetary policy shocks in Tunisia over the 1997-2015 and to provide information concerning the evolution of the economy response to these shocks. Compared with pre

In this paper, we review the score test procedure used for testing polynomial covariate effects in a semi parametric additive mixed model. This test is based on the mixed model representation of the smoothing spline estimator of the nonparametric fun

The mixed linear models are frequently used in the studies of research in medicine and social science. In this article, we presented the method of robust maximum likelihood for estimating the parameters of these models. Since this method is sensitive
