Abstract

fetched live from OpenAlex

The computer package LIFEHIST written by the author is meant for analyzing life histories through a state space approach. Basic ideas on which the various programs have been built are described in this paper in a nonmathematical language. Users can use various programs for multistate analyses based on Markov and semi-Markov frameworks and sequences of transitions implied in life histories. The package is under constant revision, and programs for using a few specific models the author thinks will be useful for analyzing longitudinal data will be incorporated in the near future.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

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.
