Hybrid Machine Learning for Used Car Price Determinants
This study develops a methodological framework for used car valuation through comparative analysis of regression techniques. Initial factor significance evaluation was conducted using Multiple Linear Regression (MLR) and Logistic Regression (LR), identifying ten key pricing determinants. Twelve regression models were subsequently implemented with these predictors, revealing LR's superior performance over MLR in coefficient stability and interpretability. The predictive phase comparatively evaluates Gradient Descent (GD) and Support Vector Machine (SVM) algorithms, with systematic residual analysis demonstrating SVM's optimal prediction accuracy. The findings provide empirical guidance for machine learning applications in automotive residual value estimation.

Comprehensive Valuation Framework
This study establishes a robust framework for used car valuation by systematically comparing various machine learning regression techniques. It begins with identifying key price determinants, followed by implementing and evaluating different regression and predictive models to ascertain optimal performance.
The process ensures a data-driven approach to understanding automotive residual values, providing actionable insights for market analysis and pricing strategies.
Regression Model Performance
Initial factor significance was evaluated using Multiple Linear Regression (MLR) and Logistic Regression (LR), revealing ten key pricing determinants. Subsequent implementation of twelve regression models demonstrated LR's superior performance in terms of coefficient stability and interpretability over MLR. The best performing log-linear model (LIM6) achieved an Adjusted R-squared of 0.846, indicating strong explanatory power for used car prices.
Key findings highlight the significant influence of factors such as vehicle age and odometer readings, which emerged as principal explanatory variables for price determination.
Predictive Algorithm Evaluation
The predictive phase focused on comparing Gradient Descent (GD) and Support Vector Machine (SVM) algorithms. Through systematic residual analysis, SVM demonstrated optimal prediction accuracy. Its ability to handle non-linear relationships and avoid overfitting contributed to its superior performance, making it a powerful tool for precise residual value estimation in the automotive market.
This comparative analysis provides empirical guidance for selecting appropriate machine learning models for practical applications in real-world scenarios.

Key Determinants of Used Car Prices
The study clearly identified several critical factors influencing used car prices. Vehicle Age and Odometer readings emerged as the principal explanatory variables, exhibiting a strong inverse proportionality with market price. Newer cars with lower mileage consistently commanded higher valuations, aligning with practical market observations.
Other significant determinants included Body Type (SUVs generally commanded premium pricing), Transmission Type (automatic variants maintained measurable price premiums), and Fuel Type (diesel-powered vehicles sustained elevated average valuations). Surprisingly, engine size showed no significant proportional relationship to price, suggesting other valuation determinants outweigh engine specifications in this dataset.
