Robust and Consistent Estimates of Autoregressive-Moving Average Parameters
自回归移动平均参数的稳健一致估计
We aim at estimates of autoregressive-moving average parameters which are simultaneously consistent at the nominal Gaussian model and insensitive to outliers in the data. The estimates may be viewed as a robust version of maximum likelihood estimates of order r and, for purely autoregressive models, reduce to a special case of generalized M-estimates.
