摘要：

Let sigma(2) be the unknown error variance of a linear model and let (sigma) over cap (2) be the estimator of sigma(2) based on the residual sum of squares. In this work, we show the precise asymptotics in the law of the logarithm for the first moment of the error variance estimator. (C) 2007 Elsevier Ltd. All rights reserved.
