of correlation between the different variables in the model. One way to address this problem is using
cross-validation. In cross-validation the data set is randomly divided into a two parts, where one part is
used for estimating the model and the other part is used for validation. Examples of validation can be
seen in two studies led by Simon Washington FOXBORO P0922YU approach is to use relative goodness of fit measures such as the Akaike Information Criterion
(AIC) and Bayesian Information Criterion (BIC) that penalize models with more estimated parameters.
Low sample mean and small sample size
Since crashes are fortunately rare events, it is not uncommon to find situations where some roadwayFOXBORO P0922YU
sections or intersections may have very few crashes, with many sites having zero crashes (i.e., with low
sample mean). These types of data may cause problems in estimation and some models may not
converge. In addition, Lord (2006) found that the overdispersion parameter that is estimated as part of
a negative binomial model can be biased when the sample mean is very low. At this time, there are fewFOXBORO P0922YU
solutions to this problem, except for a method suggested by Elvik (2011a) that involves “selecting a
subsample with even lower mean value than the full sample and estimate model coefficients for the
subsample” to see if the parameter estimates and the overdispersion parameter are stableFOXBORO P0922YU.
Bias due to aggregation, averaging, or incompleteness in data
It is common that prediction models are based on summary data based on annual or monthly totals (i.e.,
aggregated data). Elvik indicates that the “use of data that are aggregated, averaged, or incomplete can
