Optimal interpolation designs are given for estimation of the value of a linear functional of an unknown polynomial mean. For example, optimal designs are given for estimation of the average value of a multivariate polynomial over a sphere of radius a r when observations are available only in...

An algorithm and error analysis are presented for finding the maximum likelihood estimator of the noncentrality parameter of the [chi]2 and F distributions.

Speckman developed a minimax linear estimator robust against departures from an assumed model. Some concomitant questions of optimal design are investigated.
