Abstract:

Based on linear models, the inference about the true measurement equ1 and the optimal designs equ2 for the calibration experiment are considered via Bayesian statistical decision analysis. The posterior distribution of equ3 given the observation equ4 and the calibration experiment is obtained with normal priors for equ5 and for the model parameters equ6. This posterior distribution is not in the form of any known distributions, which leads to the use of a numerical integration or an approximation for the calculation of the overall expected loss. The general structure of the expected loss function is characterized in the form of a conjecture. The near-optimal design is obtained through the approximation of the conditional covariance matrix of the joint distribution of equ7. Numerical results for the univariate case are given to demonstrate the conjecture and to evaluate the approximation.
