• Matrix series
• Partial grey derivative
• Partial grey model

To solve grey impact factor in matrix series, an improved Partial Grey Model based on PGM(1,3), called PGM(1,3+m(2)), is proposed here. Meanwhile, partial grey derivative is introduced. Finally, an example is used to illustrate that PGM(1,3+m(2)) is superior to the existing grey models when simulating or predicting the multi-stream or long data series.
