Discrete Univariate Grey Prediction Model

The whitenization univariate grey prediction model, represented by GM (1,1) and TWGM (1,1), is composed of the basic form with the characteristics of difference and the whitenization equation with differential features. The basic form of the model is used for model parameter estimation, while the whitenization equation of the model is used for the derivation and solution of its time response function. Therefore, the whitenization univariate grey prediction model has both the charateristics of difference and differential.
