The Nonlinear Approach to Linear Calibration Intervals Academic Article uri icon

abstract

  • It is shown that a nonlinear approach to single use calibration curves gives reasonable intervals. The nonlinear approach produces intervals even when the classical approach fails to do So. The intervals obtained with the nonlinear approach are always slightly shorter, but the coverage rate remains reasonable, as demonstrated in the simulations. The advantages of the nonlinear approach are that intervals are centered at the maximum likelihood estimator (MLE) and that they can be obtained using any standard statistical package which contains nonlinear regression methods.
