关于两指标ARMA过程的谱密度
ON THE SPECTRUM OF ARMA PROCESS WITH TWO PARAMETERS ON SPATIAL LATTICE
【摘要】 考察了两指标ARMA过程的模型(差分方程)与其谱密度之间的关系.
【Abstract】 The relationship between the model of ARMA process and its spectrum is studied in this paper, and a result which show us that the model can be by the spectrum and vice versa is obtained.
