Applying the heteroskedastic ordered probit model on injury severity for improved age and gender estimation

CONCLUSIONS: The results of the two applied approaches revealed that HETOP model outperformed the standard OP model when measuring the effects of age and gender together in injury severity analysis, due to the heteroskedasticity in injury severity within gender and age. The HETOP statistical method presented in this paper can be more broadly applied across other contexts and combinations of independent variables for improved model prediction and accuracy of causal variables in traffic safety.PMID:38019532 | DOI:10.1080/15389588.2023.2286429
