Post-Coma Recovery of IQ
Wong data frame has 331 row and 7 columns. The observations are longitudinal
data on recovery of IQ after comas of varying duration for 200 subjects.
This data frame contains the following columns:
patient ID number.
number of days post coma at which IQs were measured.
duration of the coma in days.
a factor with levels
in years at the time of injury.
performance (i.e., mathematical) IQ.
The data are from Wong, Monette, and Weiner (2001) and are for 200 patients who sustained traumatic brain injuries resulting in comas of varying duration. After awakening from their comas, patients were periodically administered a standard IQ test, but the average number of measurements per patient is small (331/200 = 1.7).
