Decision Type:

Method Category:

Categories: Terms

An optimal design that minimizes the maximum variance of predicted values over the design region.

Alternative Meanings:

𝒟-optimal design
An optimal design that maximizes the determinant of 𝑋′𝑋, where 𝑋 is the design matrix. Useful to produce high precision regression parameter estimates.
𝐴-optimal design
An optimal design that maximizes the trace of 𝑋′𝑋, where 𝑋 is the design matrix. This is useful to minimize the sum of the variances of the different regression coefficient estimators.
