Nonlinear statistical modelling of high frequency ground ozone data
The problem of describing hourly data of ground ozone is considered. The complexity of high frequency environmental data dynamics often requires models covering covariates, multiple frequency periodicities, long memory, non linearity and heteroscedasticity. For these reasons we introduce a parametric model which includes seasonal fractionally integrated components, self exciting threshold autor...
متن کاملModelling Above ground net primary production of Sabalan rangelands using vegetation index and non-linear regression
Background and objectives: Alongside with the progresss in satellite sensors, their role on obtaining information and study of the environmental events and phenomena have become increasingly important. One of these precious data which is the basis for many planning and decision making in rangelands, is the above ground net primary production assements. The traditional method of estimating ANPP ...

15 صفحه اولGranular RBF NN Approach and Statistical Methods Applied to Modelling and Forecasting High Frequency Data
We examine the ARCH-GARCH models for the forecasting of the bond price time series provided by VUB bank and make comparisons the forecast accuracy with the class of RBF neural network models. A limited statistical or computer science theory exists on how to design the architecture of RBF networks for some specific nonlinear time series, which allows for exhaustive study of the underlying dynami...
متن کاملValidation of Damage Identification Using Non-Linear Data-Driven Modelling
As pointed out in the previous part, it is an important goal to design and construct safe, ecological and reliable structures, which are still cost effective. In order to guarantee these requirements, especially in industries where the component reliability is crucial, regular inspection intervals must be defined. As traditional inspection techniques can be very expensive in terms of both man h...
