Abstract
A method for assessing whether or not the character of a value, measured by a sensor, of a physical parameter of a device is normal. The method includes implementing steps of calculating, on the basis of a regression model associated with the plurality of pairs, an estimated value of the physical parameter; calculating a related remainder calculating, on the basis of a variance model related to the plurality of pairs, an estimated value of a variance in the physical parameter; calculating an anomaly score of the measured value on the basis of the remainder, calculating the estimated value of the variance, and calculating a mean remainder value for the plurality of pairs; comparing the anomaly score of the measured value with a standard deviation threshold; and if the anomaly score is greater than the threshold, identifying the measurement as abnormal on the interface.
