icrit {optedr}

Criterion function for I-Optimality

Description

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

\phi_I = Tr(M^{-1} \cdot B)

Usage

icrit(M, matB)

Arguments

M

information matrix for which the criterion value wants to be calculated.

matB

matrix of the integral of the information matrix over the interest region. Identity matrix for A-Optimality.

Value

Numeric value of the I-optimality criterion for the information matrix.
