For most years since 1973, results suggest that the DMF includes 93 percent to 96 percent of deaths of individuals aged 65 or older. Although studies have shown that the National Center for...
متن کاملGauge Poisson representations for birth/death master equations
Poisson representation techniques provide a powerful method for mapping master equations for birth/death processes — found in many fields of physics, chemistry and biology — into more tractable stochastic differential equations. However, the usual expansion is not exact in the presence of boundary terms, which commonly occur when the differential equations are nonlinear. In this paper, a gauge ...

METHODS: The authors used the SSA Death Master File to determine the mortality status of 374 dece...
متن کاملConsequences for healthcare quality and research of the exclusion of records from the Death Master File.
removed ≈5% of death records from its Death Master File and started excluding ≈40% of new death records, having determined that data submitted electronically by states cannot be publicly shared. Before this determination , the Death Master File provided an accessible source of national vital status data with a short time lag and high specificity and sensitivity and was routinely used by healthc...
