本程序可以完成功率谱估计中，ARMA模型的阶数估计

本程序可以完成功率谱估计中，ARMA模型的阶数估计-This procedure can be completed in the power spectrum estimation, ARMA model order estimate

ARMA有理谱估计的阶数估计，用于估计用ARMA过程估计功率谱时要用几阶比较合适。-ARMA spectrum order estimation. It is used to compute the order of ARMA process that suited for signal estimation.
