void QCCumSumChart(TMtx *Data, TVec *DrawVec, double k, double h, double mean, double sigma = 1.0, TVec *SHigh = null, TVec *SLow = null, double Confidence = 0.997);
CUMSum chart.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Data | TMtx * | Each Data row contains replicated observation taken at specific time. |
| 2 | DrawVec | TVec * | Returns values to be drawn. |
| 3 | k | double | Design parameter of the V-mask. k is the rise in the V-arm corresponding to one sampling unit. |
| 4 | h | double | Design parameter of the V-mask. h defines the rise in the arm coresponding to the distance from the origin to point vertex. |
| 5 | mean | double | Defines the estimate of the in-control mean. |
| 6 | sigma = 1.0 | double | Defines known (or estimated) standard deviation of the sample means. |
| 7 | SHigh = null | TVec * | If set, returns high values for cumsum plot. When SHigh exceeds value h, the process is said to be out-of-control. Compare SHigh values to h to find if a process is out-of-control. |
| 8 | SLow = null | TVec * | If set, returns low values for cumsum plot. When SLow exceeds value h, the process is said to be out-of-control. Compare SLow values to h to find if a process is out-of-control. |
| 9 | Confidence = 0.997 | double | Confidence level for upper and lower control limit. Confidence must lie in the (0,1) interval. |
Remarks:
Calculates CumSum Chart drawing values and additonal values, needed for deciding if some samples are out-of-control.
