The headInjury data frame has 3121 rows and 11 columns.
The data were simulated according to a simple logistic
regression model to match roughly the clinical characteristics
of a sample of individuals who suffered minor head injuries.

age factor (0 = under 65, 1 = over 65).
amnesia before impact (less than 30 minutes = 0, more than 30 minutes =1).
(0 = no fracture, 1 = fracture).
Glasgow Coma Scale decrease (0 = no deterioration, 1 = deterioration).
initial Glasgow Coma Scale (0 = not `13', 1 = `13').
Glasgow Coma Scale after 2 hours (0 = not `15', 1 = '15').
assessed by clinician as high risk for neurological intervention (0 = not high risk, 1 = high risk).
