Extreme Value Autoregressive Model and its Applications
- 5 Downloads
This article proposes a first-order autoregressive model with Gumbel extreme value marginal distribution to analyze the time-series data. As the innovation distribution of the model does not admit a closed-form expression, the problem of estimation becomes complicated. In this article, we propose the method of conditional least squares, quasi maximum likelihood, and maximum likelihood for estimating model parameters. Simulation studies are carried out to assess the performance of these methods. Two sets of real data are analyzed to illustrate the applications of the proposed model.
