Using simulated data to explore the effects of spatial structure, sampling strategy, and statistical methods on species distribution models

The ability to map and monitor animal and plant species distributions has become more important in the context of awareness of environmental change and its effects on biodiversity (Franklin 1995; Guisan and Zimmermann 2000; Guisan and Thuiller 2005). Species distribution models (SDM) are based on the quantification of speciesenvironment relationships and have seen increasing use as the availabi...

Development of a sampling strategy and sample size calculation to estimate the distribution of mammographic breast density in Korean women.

Mammographic breast density is a known risk factor for breast cancer. To conduct a survey to estimate the distribution of mammographic breast density in Korean women, appropriate sampling strategies for representative and efficient sampling design were evaluated through simulation. Using the target population from the National Cancer Screening Programme (NCSP) for breast cancer in 2009, we veri...

Using neural network to estimate weibull parameters

As is well known, estimating parameters of the tree-parameter weibull distribution is a complicated task and sometimes contentious area with several methods vying for recognition. Weibull distribution involves in reliability studies frequently and has many applications in engineering. However estimating the parameters of Weibull distribution is crucial in classical ways. This distribution has t...

A Sampling and Analytical Approach to Develop Spatial Distribution Models for Sagebrush-Associated Species

Understanding multi-scale floral and faunal responses to human land use is crucial for informing natural resource management and conservation planning. However, our knowledge on how land use influences sagebrush (Artemisia spp.) ecosystems is limited primarily to site-specific studies. To fill this void, studies across large regions are needed that address how species are distributed relative t...
