Provide used car valuation model development, modeling, technical training and secondary development.The model is based on real used car transaction data. Commonly variables include "mileage driven, total insurance amount, maintenance amount, guide price, time to market", etc. The model can effectively avoid the similarity between "mileage driven" and "time to market" The problem that the multi-factor model cannot be effective due to variables is the ridge regression problem. On the premise that there is no market fraud (modification of the odometer, tampering with insurance records), the model's estimation accuracy of the vehicle can reach 99.5%. The data fitting in the tested price range of RMB 50,000 to RMB 250,000 is all Have a perfect performance.
