This paper explores the application of spatial models to non-life insurance data focused on multi-risk home branch. In pricing modelling and rating process, information should be considered by actuaries managers because frequencies claim sizes may vary region premium different considering this variable. addition, it is relevant examine dependence due fact that frequency claims in neighbouring r...

introduction the relationship between topography and precipitation in order to estimate the type and amount of precipitation in mountainous areas has always been of great importance for climatologists. in most of researches done based on regression model, the independent parameters such as elevation, slope, aspect, longitude and latitude have been used and the rule of distance to describe the s...

Thin plate and spherical splines are nonparametric methods suitable for spatial data analysis. Thin plate splines acquire efficient practical and high precision solutions in spatial interpolations. Two components in the model fitting is considered: spatial deviations of data and the model roughness. On the other hand, in parametric regression, the relationship between explanatory and response v...

The purpose of this study was to identify factors influencing the adoption of wheat waste management by wheat farmers. The method used in this study using the spatial Probit models and Bayesian model was used to estimate the model. MATLAB software was used in this study. The data of 220 wheat farmers in Khouzestan Province based on random sampling were collected in winter 2016. To calculate Bay...

learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
