Spatial Sampling With R

Scientific research often starts with data collection. However, many researchers pay insufficient attention to this first step in their research. The author, researcher at Wageningen University and Research, often had to conclude that the data collectedby fellow researchers were suboptimal, or in some cases even unsuitable for their aim. One reason is that sampling is frequently overlooked in statistics courses. Another reason is the lack of practical textbooks on sampling. Numerous books have been published on the statistical analysis and modelling of data using R, but to date no book has been published in this series on how these data can best be collected. This book fills this gap. Spatial Sampling with R presents an overview of sampling designs forspatial sample survey and monitoring. It shows how to implement the sampling designs and how to estimate (sub)population- and space-time parameters in R. Key features Describes classical, basic sampling designs for spatial survey, as well as recently developed, advanced sampling designs and estimators Presents probability sampling designs for estimating parameters for a (sub)population, as well as non-probability sampling designs for mapping. Gives comprehensive overview of model-assisted estimators Illustrates sampling designs with surveys of soil organic carbon, above-ground biomass, air temperature, opium poppy This book helps researchers and practitioners to implement proper sampling designs, tailored to their problems at hand, so that valuable data are collected that can be used to answer the research questions. Exercises are added, making the book suitable as a textbook for students--
