Description

Calculates the sensitivity function from the gradient vector, the Identity Matrix and the parameters of interest.

Usage

dssens(grad, M, par_int)

Arguments

grad

A function in a single variable that returns the partial derivatives vector of the model.

M

Information Matrix for the sensitivity function.

par_int

Numeric vector of the indexes of the parameters of interest for Ds-Optimality.

Value

The sensitivity function as a matrix of single variable.
