Research on The Recursive Method for Real Time Variance Calculation
In the area of manufacturing and industrial engineering, variance calculation is the basic method to monitor the performance of instrument. In this paper, the recursive formula of real-time variance calculation is been put forward. Then it is possible to calculate the variance at real time without save the historical data. Experiment results shows that the new method for calculate the variance can greatly improve the calculating efficiency with high precision.
