Abstract
The efficiency in estimating the mean of a weakly stationary process is investigated. Estimators M n λ are optimum provided the spectral density has a zero in t = 0 of order λ. Here we study the asymptotic behavior of M n λ in case the spectral density has a zero in t = 0 of order different from λ. In particular we prove that M n λ are optimum if λ is greater than this order.
