burg.

  burg法估计AR（P)模型参数的算法。里面ef是前项误差bf是后项误差，mse是预测误差的均方值。程序的最后输出的是把各阶预测误差放在一个下三角距阵中(burg estimates the AR (p) model parameter algorithm. Ef is inside the former bf error is the latter error, mse is forecast error of the mean square value. Procedures for the final output stage is the prediction error on a triangular matrix under which)
