Abstract
Abstract The authors examine multistate current status data defined by two survival times of interest where one only observes whether or not each of the individual survival times exceed a common observed monitoring time. An individual can therefore belong to one of three states. The authors are interested in whether current status information on the second event can be used to improve estimation of the distribution function of time to the first event. For both single and multiple monitoring time scenarios, in the fully nonparametric setting, one cannot improve the naïve estimator, using information on the first event only, when estimating “smooth” functionals of the distribution of time to the first event (van der Laan & Jewell, 2003). Therefore, improving the naïve estimator is examined when parametric assumptions about the waiting time between the two events are made. For situations where this waiting time is modifiable by design, the issue of determining the optimal length of the waiting time for estimation of the cumulative hazard of the distribution of time to the first event in the recent past is also addressed. The ideas are motivated by and applied to an example on simultaneous accurate and diluted assay HIV test data.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
