Abstract

fetched live from OpenAlex

Based on the weekly price data about supervision on the “early warning system of live pig production in Sichuan Province”, this article made a dynamic analysis in the research objects of live pig price, corn price, piglet price and pork retail price, including cointegration relationship test, Granger causality test and impulse response analysis so as to analyze the long term and short term conduction effects among different variables within the system of live pig system. It was discovered from the cointegration analysis that, the conintegration relationship existed within the live pig price system in Sichuan Province. In the long run, influence of piglet price on price fluctuation of live pig price was greater than that of corn price. The opposite is true to the short run. It was discovered through Granger test that, within a single production cycle (4 to 6 months), the piglet price, corn price and pork price affected the live pig price under Granger significance, while corn price and piglet price were exogenous to the system. It was discovered through the impulse response analysis that within a single production cycle, impact of the live pig price on price fluctuation of piglet manifested a “positive-negative-positive” response, mostly a “negative” response on price fluctuation of pork and mostly a “positive” response on price fluctuation of corn price. Finally, the authors put forward suggestions of decomposition of interest of the live pig industrial chain and escalation of value, etc.

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.
