Characteristic function-based inference for GARCH models with heavy-tailed innovations
(Taylor & Francis, 2017)We consider estimation and goodness-of-fit tests in GARCH models with innovations following a heavy-tailed and possibly asymmetric distribution. Although the method is fairly general and applies to GARCH models with arbitrary ... -
Fourier-type estimation of the power GARCH model with stable-Paretian innovations
(Springer, 2016)We consider estimation for general power GARCH models under stable-Paretian innovations. Exploiting the simple structure of the conditional characteristic function of the observations driven by these models we propose ... -
Goodness-of-fit tests for parametric specifications of conditionally heteroscedastic models
(Springer, 2020)We consider a goodness-of-fit test for certain parametrizations of conditionally heteroscedastic time series with unobserved components. Our test is quite general in that it can be employed to validate any given specification ...
