The asymptotic distribution of the Gaussian quasi-maximum likelihood estimator (QMLE) is obtained for a wide class of asymmetric GARCH models with exogenous covariates. The true value of the parameter is not restricted to belong to the interior of the parameter space, which allows us to derive...

This paper advocates the transformations used for the consistent estimation of the full-fledged fixed effects zero-inflated Poisson model whose zero outcomes can arise from both of logit and Poisson parts and which equips both parts with the fixed effects. The valid moment conditions are...
