Query: Self-reporting and screening: Data with current-status and censored
  observations   We consider survival data that combine three types of observations:
uncensored, right-censored, and left-censored. Such data arises from screening
a medical condition, in situations where self-detection arises naturally. Our
goal is to estimate the failure-time distribution, based on these three
observation types. We propose a novel methodology for distribution estimation
using both parametric and nonparametric techniques. We then evaluate the
performance of these estimators via simulated data. Finally, as a case study,
we estimate the patience of patients who arrive at an emergency department and
wait for treatment. Three categories of patients are observed: those who leave
the system and announce it, and thus their patience time is observed; those who
get service and thus their patience time is right-censored by the waiting time;
and those who leave the system without announcing it. For the third category,
the patients' absence is revealed only when they are called to service, which
is after they have already left; formally, their patience time is
left-censored. Other applications of our proposed methodology are discussed.
