Quality control is an important role in industry for maintain quality stability. Statistical process can quickly investigate the occurrence of unforeseen causes or shifts using charts. Mixed Exponentially Weighted Moving Average - Cumulative Sum (MEC) chart a tool used to monitor and evaluate whether production not. The MEC method combination (EWMA) (CUSUM) Combining two charts aims increase se...

We introduce QuantTree Exponentially Weighted Moving Average (QT-EWMA), a novel change-detection algorithm for multivariate datastreams that can operate in nonparametric and online manner. QT-EWMA be configured to yield target Run Length (ARL\(_0\)), thus controlling the expected time before false alarm. Control over alarms has many practical implications is rarely guaranteed by algorithms moni...
