Our recent work to use spatial microsimulation techniques to estimate health parameters in the state of Idaho is now accessible in the journal, Population, Space and Place. Our BRFSS modeling work uses population synthesis and microsimulation techniques to estimate health indicators at a county level. Our recent focus has been on applications to data for the state of Idaho – but our ongoing research is exploring alternative regions, additional health indicators, and differing techniques (geographically weighted regression, simulated annealing) to improve performance.
