Overview

Comparative analysis shows predictive capability of morphometric traits in Corriedale lambs, suggesting stability in machine learning models.

Key Points

  • Models demonstrated excellent predictive capability with a coefficient of determination R2 = 0.89, showing strong predictive accuracy for live weight.
  • Multiple linear regression and Ridge regression achieved the lowest mean squared error of MSE = 0.083, indicating their high stability in predictions.
  • Assessment included various algorithms such as decision trees and XGBoost to evaluate their effectiveness in live weight prediction.
  • Findings highlight the importance of using balanced models for precise feed allocation and monitoring growth in sheep production.
