Variance exchange process: overcoming the problem of singular information matrices in quadratic three−variable response designs
Many a time, in a variance exchange process looking for D-optimal designs, the initial designs of all quadratic components of three-variable response polynomials produce non-invertible information matrices. For such matrices, the variances of predicted responses at variance points cannot be evaluat...
