U.S. Department of Health and Human Services, National Institutes of Health, National Cancer Institute announces the availability of funding for implementation of the Spatial Uncertainty: Data, Modeling, and Communication (R21) Exploratory/Developmental Research Grant. The purpose of this grant is to support innovative research that identifies sources of spatial uncertainty (i.e., inaccuracy or instability of spatial or geographic information) in public health data, incorporates the inaccuracy or instability into statistical methods, and develops novel tools to visualize the nature and consequences of spatial uncertainty. The R21 activity code is intended to encourage new exploratory and developmental research projects . . .
