Highway Accidents Statistical Analysis With Panel Data Model

Models, which employ panel data analysis to model highway crashes, can identify fixed differences and other unobserved factors in real world.This paper introduces process of individual fixed-effects and random-effects models and related tests.These models are applied to Jingjintang highway.Pool data regression, models of fixed effects and random effects are established respectively.Hausman results show that fixed-effect model is better than others when describing the relationship between accidents and other factors.
