Query: Some overview on unbiased interpolation and extrapolation designs   This paper considers the construction of optimal designs due to Hoel and
Levine and Guest. It focuses on the relation between the theory of the uniform
approximation of functions and the optimality of the designs. Some application
to accelerated tests is also presented. The multivariate case is also handled
in some special situations.
