Abstract:
|
A new bivariate control chart denoted by T2 MEDMAD based on the robust estimation as an alternative to the Hotelling's T2 control chart is proposed. The location vector and the variance-covariance matrix for the new control chart are obtained using the sample median, the median absolute deviation from the sample median, and the comedian estimator. The performance of the proposed method in detecting outliers is evaluated and compared with the Hotelling's T2 method using a Monte-Carlo simulation study. To illustrate the application of the proposed method we will discuss a numerical example.
