Criterion function for Ds-Optimality

Description

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

\phi_{Ds} = \left(\frac{|M_{22}|}{|M|}\right)^{1/s}

Usage

dscrit(M, par_int)

Arguments

M	information matrix for which the criterion value wants to be calculated.
par_int	numeric vector with the index of the parameters of interest of the model.
