Abstract

fetched live from OpenAlex

Credit migration matrices are often used in many credit risk and pricing application, and typically assumed to be generated by a simple Markov process. This paper is going to analyze the basic elements of credit risk research, and Maximum Likelihood estimation will be adopted to estimate the Mover-Stayer model’s parameters in this paper. Furthermore, the recursive method will be used to compute the Maximum Likelihood estimator, and the numerical results can illustrate the strength of the Mover-Stayer model on credit risk analysis. We also use the hypotheses to prove that the Markov chain suit for the data against the hypotheses that the Mover-Stayer model more suitable for the data. Finally, we will make some comparisons according to the output of the program, and obtain some conclusions. The Mover-Stayer Model is more suitable against according the numbered result.

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.
