A simulation study of the covariance and correlation properties of the Fractionally Integrated Separable Spatial Autoregressive (FISSAR) model
Spatial modelling has its applications in many fields. In time series, there exists a class of models known as long memory models, where the autocorrelation function decays rather slowly. These types of time series data are modelled as fractionally integrated ARMA processes. Spatial data may also ex...

description | Spatial modelling has its applications in many fields. In time series, there exists a class of models known as long memory models, where the autocorrelation function decays rather slowly. These types of time series data are modelled as fractionally integrated ARMA processes. Spatial data may also exhibit a long memory structure and in order to model such structure, a class of models called as the NFractionally Integrated Separable Spatial Autoregressive (FISSAR) Model has been introduced. The objectives of this research are to demonstrate on how to simulate a FISSAR (1, 1) process, to examine the properties of the variance
estimator and to illustrate the correlation properties. |
