Weighted Least Absolute Deviations Estimation for Periodic ARMA Models被引量:1
《Acta Mathematica Sinica,English Series》2015年第8期1273-1288,共16页Baoguo PAN Min CHEN Yan WANG 
Supported by National Natural Science Foundation of China(Grant Nos.10990012 and 11021161)
This paper investigates the weighted least absolute deviations estimator(WLADE) for causal and invertible periodic autoregressive moving average(PARMA) models. Asymptotic normality of the estimator is derived unde...
