FIM_exp_2par {ICAOD}

Fisher Information Matrix for the 2-Parameter Exponential Model

Description

It provides the cpp function for FIM for the model ~a + exp(-b*x).

Usage

FIM_exp_2par(x, w, param)

Arguments

x

Vector of design points.

w

Vector of design weight. Its length must be equal to the length of x and sum(w) = 1.

param

Vector of values for the model parameters c(a, b).

Details

The FIM does not depend on the value of a.

Value

Fisher information matrix.
