The TIME statement names the variables that represent the interval-censored observations. The variables should be numeric.
For example, the following statement identifies Left
as the lower bound and Right
as the upper bound of an observed interval:
time (Left, Right);
Observations for which Left
Right
and both values are nonnegative are used. If the value for Left
is missing or 0 and the value for Right
is not missing, then the observation is treated as left-censored. If the Right
value is missing and the value for Left
is not missing, then the observation is treated as right-censored. Observations for which both variables are missing are
not analyzed.
