Abstract
The purpose of this research is to develop a target cost model for the Main Landing Gear at Bombardier Aerospace. This will offer a cost understanding at the early conception stage. The study uses a comparative analysis between a linear and a non-linear parametric model in order to determine which estimation method will increase the credibility of the cost estimate. The reliability of the models will be validated by two different methodologies to determine which parameter(s) become significant and will therefore be used to determine the cost. These methodologies are the analysis of variance and path analysis. It was found that the non-linear regression analysis achieves a lower level of error when comparing it to the linear regression.

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
