This study present a hybrid method of estimating VAR, combining Neural Network and ARMA. Empirical results demonstrate that the hybrid method obtained superior results to the conventional method in estimating VAR. When applied to the Shanghai stock market both the conventional and hybrid methods performed well in terms of accuracy, with the only poorly performing result being the HS method in S...

We introduce a generic framework for hybrid logics, i.e. modal logics additionally featuring nominals and satisfaction operators, thus providing the necessary facilities for reasoning about individual states in a model. This framework, coalgebraic hybrid logic, works at the same level of generality as coalgebraic modal logic, and in particular subsumes, besides normal hybrid logics such as hybr...
