We study strategically missing data problems in predictive analytics with regression. In many real-world situations, such as financial reporting, college admission, job application, and marketing advertisement, data providers often hide certain information on purpose in order to gain a favorable outcome. It is important for the decision maker to have a mechanism to deal with such strategic behaviors. We propose a novel approach, based on the Support Vector Regression (SVR) technique, to handle strategically missing data in regression prediction. The proposed method derives the imputed values of missing data based on the margins of the SVR models. It provides incentives for the data providers to disclose their true information. We show that imputation errors for the missing values are minimized under some reasonable conditions. Furthermore, with the proposed method, the decision maker’s decision models will not be affected by strategic behaviors of data providers. An experimental study on real-world data demonstrates the effectiveness of the proposed approach.
