Quantifying the Effect of Area Deprivation on Child Pedestrian Casualties by Using Longitudinal Mixed Models to Adjust for Confounding, Interference and Spatial Dependence
Bibliographic record
Abstract
Summary The paper investigates the link between area-based socio-economic deprivation and the incidence of child pedestrian casualties. The analysis is conducted by using data for small spatial zones within major British cities over the period 2001–2007. Spatial longitudinal generalized linear mixed models, estimated by using frequentist and Bayesian approaches, are used to address issues of confounding, spatial dependence and transmission of deprivation effects across zones (i.e. interference). The results show a consistent strong deprivation effect across model specifications. The incidence of child pedestrian casualties in the most deprived zones is typically greater than 10 times that in the least deprived zones. Modelling interference through a spatially auto-regressive covariate uncovers a substantially larger effect.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
