A spatial sampling optimization package using MSN theory
نویسندگان
چکیده
The density and distribution of spatial samples heavily affect the precision and reliability of estimated population attributes. An optimization method based on Mean of Surface with Nonhomogeneity (MSN) theory has been developed into a computer package with the purpose of improving accuracy in the global estimation of some spatial properties, given a spatial sample distributed over a heterogeneous surface; and in return, for a given variance of estimation, the program can export both the optimal number of sample units needed and their appropriate distribution within a specified research area. 2010 Elsevier Ltd.

Linear Quantile Mixed Models: The lqmm Package for Laplace Quantile Regression
Inference in quantile analysis has received considerable attention in the recent years. Linear quantile mixed models (Geraci and Bottai 2014) represent a flexible statistical tool to analyze data from sampling designs such as multilevel, spatial, panel or longitudinal, which induce some form of clustering. In this paper, I will show how to estimate conditional quantile functions with random eff...
متن کاملSpatioTemporal: An R Package for Spatio-Temporal Modelling of Air-Pollution
Modelling of Gaussian spatio-temporal processes provide ample opportunity for different model formulations, however two principal directions have emerged. The data can be modelled either as a set of spatially varying temporal basis functions or as spatial fields evolving in time. This package provides maximum-likelihood estimation and crossvalidation tools for the first case. Development of the...
متن کاملEvaluation of Sampling Methods for Validation of Remotely Sensed Fractional Vegetation Cover
Validation over heterogeneous areas is critical to ensuring the quality of remote sensing products. This paper focuses on the sampling methods used to validate the coarse-resolution fractional vegetation cover (FVC) product in the Heihe River Basin, where the patterns of spatial variations in and between land cover types vary significantly in the different growth stages of vegetation. A samplin...
متن کاملRELIABILITY-BASED MULTI-OBJECTIVE OPTIMAL DESIGN OF SPATIAL TRUSSES USING GAME THEORY AND GA
This paper introduces a reliability-based multi-objective design method for spatial truss structures. A multi-objective optimization problem has been defined considering three conflicting objective functions including truss weight, nodal deflection, and failure probability of the entire truss structure with design variables of cross sectional area of the truss members. The failure probability o...
