模型预测准确度分析及改进建议

As previously mentioned, although the model accuracy is acceptable, the prediction accuracy for samples with a response variable category of 1 is extremely low. Therefore, further improvement or consideration of other models is needed to improve the applicability of the results obtained from this model. In the process of model construction, a simple and direct deletion method was used to handle NA and outlier data to simplify the construction steps. However, this may lead to the model missing some possible key information to a certain extent.
