dcrit: Criterion function for D-Optimality

In optedr: Calculating Optimal and D-Augmented Designs

Criterion function for D-Optimality

Description

Calculates the value of the D-Optimality criterion function, which follows the expression:

φ_D = ≤ft(\frac{1}{|M|}\right)^{1/k}

Usage

dcrit(M, k)

Arguments

M	information matrix for which the criterion value wants to be calculated.
k	numeric variable with the number of parameters of the model. Taken from the number of rows of the matrix if omitted.

Value

numeric value of the D-optimality criterion for the information matrix.
