Such an estimator can be found in the literature in the case where the measurement field is a right parallelotope. In this paper, this estimator is extended to apply to measurement fields of various shapes, and to possess a smaller variance.
Anderson (1984) demonstrated that (i) det(W) corresponds geometrically to the volume of a parallelotope in n-dimensions whose edges are the column (attributes) vectors of X and (ii) the cosine of the angle between each pair of these vectors is the correlation coefficient between the corresponding attributes.
The volume of the parallelotope generated by the vectors [[??].sub.1], [[??].sub.2], ..., [[??].sub.k] [member of] RI is given by the associated Gram determinant.
