ESTIMATING AUTOCOVARIANCE OF IN SITU SOIL PROPERTIES. DISCUSSION AND CLOSURE

A discussion of a paper with the aforementioned title by DeGroot and Baecher, published in this journal (Volume 119, Number 1, January 1993), is presented. The discussion focuses on the technique of maximum likelihood estimation. Li notes the possibility of local maxima existing in the log-likelihood function when using the maximum-likelihood-estimation technique. In the presence of multiple local maximums, a sophisticated optimization technique may be needed to ensure that the global maximum value of the log-likelihood function is obtained. Discussion is followed by closure from the authors.
