Summary
Constructs nP-Chart.
Unit
StatControlCharts
Declaration
Procedure QCNPChart(Data: TVec; SampleSize: TVec; DrawVec: TVec; CL, UCL, LCL: TVec; Confidence: TSample);
| Parameter | Description |
|---|
| Data | Data to be analyzed. Each value represents number of defects. |
| Confidence | Confidence level for upper and lower control limit. Confidence must lie in the (0,1) interval. |
| Samplesize | Sample size. Can be integer or vector. |
| DrawVec | Returns values to be drawn. |
| CL | Returns control Chart centerline. |
| UCL | Returns control Chart upper control limit. |
| LCL | Returns control Chart lower control limit. |
Description
In this case each sample can have different size. You must store sizes in SampleSize vector. An exeption is raised if Data and SampleSize length do not match.

Declaration
Procedure QCNPChart(Data: TVec; SampleSize: Integer; DrawVec: TVec; out CL, UCL, LCL: TSample; Confidence: TSample = 0.997);
Description
Constructs nP-Chart drawing values, center line, upper and lower control limit. The assumption is all samples have the same SampleSize.
