In order to recognize psychological crisis of college students effectively, according to the education statistics theory, a classification method based on dominance relation is used and a double limited dominance rough set approach and calculation method for early warning information system of psychological crisis of college students is established in this paper. According to the known properties values of each attribute of information system, the probability distribution is calculated. And the probability threshold is selected and compared with the obtained advantages of probability to realize the dominance relation judgment between each object. In addition, a comprehensive comparison and analysis of attribute reduction effect under different threshold probability is made to obtain the main factors of psychological crisis of college students.
According to the questionnaire survey and comparative analysis and calculation, it indicates that the obtained simplified results is more applicable, and has higher accuracy and a lower error rate of classification.
