Ranking, rating and scoring of tourism journals: Interdisciplinary challenges and innovations

This paper provides a critical analysis of journal ranking and citation analysis in tourism studies. Authors and institutions using journal impact factors, citation frequency and hits as measures of academic productivity or importance should exercise great care in their use. A close look at Journal Citation Reports produced by Social Science Citation Index, ‘hits’ on CAB International, and cita...

Estimation des modèles VARMA structurels avec innovations linéaires non corrélées mais non indépendantes

The asymptotic properties of the quasi-maximum likelihood estimator (QMLE) of vector autoregressive moving-average (VARMA) models are derived under the assumption that the errors are uncorrelated but not necessarily independent. Relaxing the independence assumption considerably extends the range of application of the VARMA models, and allows to cover linear representations of general nonlinear ...

Integer Valued AR(1) with Geometric Innovations

The classical integer valued first-order autoregressive (INA- R(1)) model has been defined on the basis of Poisson innovations. This model has Poisson marginal distribution and is suitable for modeling equidispersed count data. In this paper, we introduce an modification of the INAR(1) model with geometric innovations (INARG(1)) for model- ing overdispersed count data. We discuss some structu...
