MORE RESULTS ON PRODUCT MOMENTS FROM A FINITE UNIVERSE.

In a previous paper [4] an estimate of the 4-variate product moment E[{x[sub I] - E(x[sub I])} {x[sub j] - E(x[sub j])} {x[sub k] - E(x[sub k])} {x[sub h] - E(x[sub h])}] was obtained. This estimate had a slight bias, as we pointed out. In this paper an unbiased estimate of the 4-variate product moment is obtained. Asymptotic results for the 3-variate and 4-variate product moments and their estimates are also obtained. [ABSTRACT FROM AUTHOR]
