Since incident-level homicide datasets, such as the Supplementary Homicide Reports (SHR), commonly exhibit missing data, the current study evaluated multiple imputation methods (that produce multiple completed datasets, across which imputed values may vary) via unique data that included actual values from police agency incident reports of seemingly missing SHR data.
This permitted evaluation under a real, not assumed or simulated, missing data mechanism. The study compared analytic results based on multiple imputed and actual data; multiple imputation rather successfully recovered victim-offender relationship distributions and regression coefficients that hold in the actual data. Results are encouraging for users of multiple imputation, though it is still important to minimize the extent of missing information in SHR and similar data. (publisher abstract modified)
