crit {optedr}

Master function for the criterion function

Description

Depending on the Criterion input, the function returns the output of the corresponding criterion function given the information matrix.

Usage

crit(Criterion, M, k = 0, par_int = 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'

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.

par_int

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

Numeric value of the optimality criterion for the information matrix.
