Abstract
In this paper, the starting conditions of GM model group are studied. By choosing the nth component of X(1) as the starting conditions of the grey differential model, improvements are made on the models. As the new information is fully used, the accuracy of prediction is improved greatly. Therefore, it has high theoretical and practical value.
