The projection relational degree model based on panel data

According to some problems in the existing relational degree models for panel data, combining the space vector projection knowledge, the new relational coefficient formula is put forward. Therefore, the panel data is projected to space vector series firstly. Then, the relational coefficient formula is detailed described, and the properties are also discussed. The projection relational degree model for panel data is proposed on the basis of the relational coefficient formula. The properties of the new model, normalization, the independence of confounding factors and relation, are also satisfied. we also give the companion with some state-of-the-art models, the experimental results show that the proposed model can more accurately reflect the relational degree for the panel data. Finally, an example is given to further verify the rationality and effectiveness of the new model.
