CONTROL CHART AS VERIFICATION TOOLS IN TIME SERIES MODEL

Control charts are generally use in quality control processes, especially the industrial sector, because they helpful to increase productivity. However, can also be used time series analysis. The residuals from model as observations constructing chart. Because there is only one variable observed, namely residual, chart Individual Moving Range (IMR). This study analysis accuracy of using IMR two models, Autoregressive Distributed Lag (ADL) without outliers and ADL with outliers. results showed that could measure model. seen statistically controlled residual (in control).
