eff {optedr}

Efficiency between two Information Matrices

Description

Efficiency between two Information Matrices

Usage

eff(Criterion, mat1, mat2, k = 0, intPars = c(1), matB = NA)

Arguments

Criterion

character variable with the chosen optimality criterion. Can be one of the following:

• 'D-Optimality'

• 'Ds-Optimality'

• 'A-Optimality'

• 'I-Optimality'

mat1

first information matrix, for the numerator.

mat2

second information matrix, for the denominator.

k

number of parameters of the model. Taken from the number of rows of the matrix if omitted.

intPars

numeric vector with the index of the parameters of interest of the model. Only for "Ds-Optimality".

matB

matrix of the integral of the information matrix over the interest region. Only for "I-Optimality".

Value

Efficiency of first design with respect to the second design, as a decimal number.
