为探讨网络编码块长度、节点移动速度、接收节点个数对基于部分网络编码的实时多播( PNCRM)协议性能的影响，提出采用稳健回归分析构建预测PNCRM协议性能回归模型的方法。利用迭代加权最小二乘法求解回归系数，并对该模型进行显著性检验。结果表明，该模型对PNCRM协议性能预测的平均相对误差仅为4.83%，因而具有较准确的预测能力。

To investigate the influences of the BlockSize, the speed of node movement, and the number of receivers on the performance of partial network coding-based real-time multicast protocol ( PNCRM ) , a model for the prediction of the performance of PNCRM was built based on robust regression analysis. The iteratively reweighted least-squares algorithm was used to solve regression coefficients. A significance test was conducted for the model. The results show that the mean relative error was only 4.83% when using the model for the prediction of the performance of PNCRM, and, thus, the model has strong prediction capability.
