Building Regression Models for Tire Design Factors

타이어 설계 인자들에 대한 회귀모형의 수립

Two regression models for explaining the tire performances (especially conering coefficients) by tire design and experimental factors are built. One is the ordinary regression model, and the explaining variables in the model are selected by a stepwise method. The other model is built by a modern nonparametric regression technique, called projection pursuit regression. Then two models are compared and combined, so that the relationship between the tire performances and design factors are well figured out. The optimal experimental design issue and future research ideas are also discussed.
