heteroscedasticity becomes biased and inconsistent. In this study, the analytical expressions for the inconsistency have been derived in … the first order autoregressive case. A comparison between asymptotic bias and small sample simulated bias has also been …

applications, small sample bias in the estimation of autoregressive coefficients is transmitted to the recoloring filter, leading … the effects of small sample autoregressive bias. Moreover, a commonly-used restriction rule on the prewhitening estimates …
