Abstract
The objective of this study is to find a suitable functional form for United States apple juice import demand and analyze import demand elasticity,using data of United States apple juice import from January in 2002 to December in 2010.Otherwise,this study considered and tested adding-up,homogeneity,symmetry,endogeneity and goodness of fit of demand system.The results show that the general model is more accurate than other models.The expenditure elasticity of the United States apple juice import demand from china is positive and significant.The own-price elasticity doesn't influence United States apple juice import demand from china significantly.The main competitor for china apple juice exporting to United States is Canada.

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
