Abstract

fetched live from OpenAlex

Abstract This study deals with the analysis of estimation of cure rate. Mixture models have been proposed for cure rate estimation. In this paper we have tried to estimate the cure parameter by considering censored data specifically for Type 2 censoring from mixture model. We have used parametric Maximum likelihood estimation (PMLE) method and non parametric maximum likelihood (NPMLE) method to estimate the parameter. From the analysis we have found an explicit solution for the parameter of cure rate model based on Type 2 censoring for known distribution function. On the other hand when the distribution function are unknown, we have found a non-parametric estimating equations for on based on Type 2 censoring scheme.

Teacher imitation

Not 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.
