FIM_2par_exp_censor1 {ICAOD}

Fisher Information Matrix for a 2-Parameter Cox Proportional-Hazards Model for Type One Censored Data

Description

It provides the cpp function for the FIM introduced in Eq. (3.1) of Schmidt and Schwabe (2015) for type one censored data.

Usage

FIM_2par_exp_censor1(x, w, param, tcensor)

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(\beta_0, \beta_1).

tcensor

The experiment is terminated at the fixed time point tcensor.

Value

Fisher information matrix.
