the program menyanthes combines a variety of functions for managing, editing, visualizing, analyzing, and modeling hydrogeologic time series. the primary aim of the software is the integration of data-driven and physics-based methods for modeling time series of groundwater heads. within menyanthes, time series can be modeled using both the arma and pirfict methods. the pirfict method is a new m...

Th e airport catchment area is the geographic from which an can reasonably expect to draw commercial air service passengers. purpose of this interdisciplinary research estimate areas using a spatial analysis method for informed management. In order ensure comprehensiveness and reliability research, we chose analyze five airports different sizes in locations United States. The Huff model, usuall...

The presence of outliers will affect the parameter estimation results and model accuracy. It also occurs in spatial regression model, especially Spatial Autoregressive (SAR) model. is a where effects are attached to dependent variable. Removing analysis eliminate necessary information. Therefore, solution offered modify SAR by giving special treatment observations that have potentially become o...

We study the class of dependence models for spatial data obtained from Cauchy convolution processes based on different types kernel functions. show that resulting have appealing tail properties, such as at short distances and independence long with suitable derive extreme-value limits these processes, their smoothness detail some interesting special cases. To get higher flexibility sub-asymptot...
