Censored Data
The first row of the completed data file contains a timesqr value of 7. Because that was
not a censored value, 7 is not an imputed value. It is just an ordinary numeric value that
was present in the original data file. On the other hand, Patient 25’s timesqr was
censored, so that patient has an imputed timesqr (in this case, 49.66.) The value of
49.66 is a value drawn randomly from the posterior predictive distribution in the figure
on p. 482.
