icrit

Calculates the value of the I-Optimality criterion function, which follows the expression:
$$\phi_I = Tr(M^{-1} \cdot B)$$

Calculates D-, Ds-, A-, I- and L-optimal designs for non-linear models, via an implementation of the cocktail algorithm (Yu, 2011, <doi:10.1007/s11222-010-9183-2>). Compares designs via their efficiency, and augments any design with a controlled efficiency. An efficient rounding function has been provided to transform approximate designs to exact designs.
