A general method for calculating the uncertainty of virtual sensors for packaged air conditioners

What is it about?

This paper discusses a method to quantify the uncertainty of virtual sensors in the same way as uncertainty of measurement: to quantify uncertainty of virtual sensors as the difference between the true values of the modeled variable and their corresponding estimation.

Why is it important?

This method is important because a) It quantifies not just the uncertainties related to the sensors but uncertainty due to the choice of experimental data to calibrate the virtual sensor and the estimation error. b) It involves uncertainty changes as a result of extrapolation of the virtual sensors.
