A note on out-of-sample prediction, marginal effects computations, and temporal testing with random parameters crash-injury severity models
Analytic Methods in Accident Research(2022)
Abstract
•Multiple random parameters logit models were estimated and evaluated.•Methods for marginal effects calculation and injury-severity prediction were proposed.•Out-of-sample simulation for random parameters was highlighted.•The testing methods for temporal instability were assessed.
